The strawberry milkshake went over somewhere near the motorway services outside Bristol. Not a small spill. A full cup, lid off, arcing through the air in what felt like slow motion, landing mostly on my daughter's lap and partly on the bag of snacks I'd carefully packed that morning. She was four. She screamed. My son, seven, announced he needed the toilet immediately. We were forty minutes from our first stop.
I pulled over on the hard shoulder, which you should not do unless it is a genuine emergency, and spent twenty minutes wiping pink sludge off a car seat with a pack of wet wipes and the sleeve of my own jumper. That was day one of a twelve-day loop from southern England down to Cornwall and back, with two kids and a boot that looked like a small branch of a discount supermarket.
We've done this trip three times now. I've got better at it. Not perfect, but better.
Why we keep doing this to ourselves
My wife and I had talked about a proper family road trip for years. The sticking point was always the same: was it actually going to be fun, or just a moving argument with a view? Friends with older kids said the trick was to stop treating the drive as dead time and start treating it as part of the holiday. That sounded like the kind of thing people say before they've spent six hours on the A30.
We went anyway. First trip was a mess. Second was decent. Third was genuinely good, and I think I finally understand why.
The first day is always a write-off
Here's the thing nobody tells you: the first day of a long drive with young kids is not a travel day. It's a survival day. You will not make the progress you planned. You will stop more often than you think.
On our last trip we aimed for roughly four hours of driving on day one. We did two and a half. That was fine once I stopped fighting it.
What helped in a practical sense was building the day around the kids' rhythms rather than the map. We left at 5:30am, which sounds brutal, but both of them slept for the first ninety minutes, and we cleared the worst traffic before it existed. If your kids are early risers, this is close to free money. If they are not, don't force it, because a screaming child at 5am is worse than traffic at 8am.
Expect around £12-£18 for a family breakfast at a motorway services if you eat there. We started bringing a flask and pastries instead. It's not glamorous. It works.
The snack strategy that changed everything
I used to pack snacks in one big bag. This was a mistake. The bag would end up upside down under a seat by hour two, and every request would turn into a rummage.
Now I pack small paper bags, one per child per leg of the journey, each with a drink, a savoury thing, a sweet thing, and one surprise. The surprise matters more than the food. It can be a sticker sheet, a tiny puzzle, a pack of cards. It costs almost nothing and buys you twenty minutes of peace.
Do not put chocolate in there in summer. I learned that one the hard way, in a hot car, in Devon.
Screens are not the enemy
I resisted this for a while. I had some vague idea that a road trip should be about scenery and conversation. Then I realised I was the only one in the car who cared about the scenery, and the conversation had run dry somewhere around junction 27.
We now allow screens, but with rules. Download everything before you leave, because data in rural areas is unreliable and roaming charges are a trap. Bring a splitter or two sets of headphones so they don't fight over volume. And have a hard stop: no screens for the last thirty minutes of any drive, so everyone arrives able to actually look at where they are.
If you're planning a longer trip abroad with kids, the same logic applies to flights. I wrote about some of this in the travel guides section, mostly because I kept making the same mistakes twice.
Where the money actually went
We budgeted for the obvious things and got caught by the small ones. Here's roughly what a twelve-day UK road trip for a family of four cost us, in 2024 prices. Treat these as estimates, not quotes, because fuel and accommodation swing a lot depending on season and how far you're going.
| Item | Rough cost for 12 days |
|---|---|
| Fuel (around 1,200 miles) | £180-£260 |
| Accommodation (mix of self-catering and budget hotels) | £900-£1,400 |
| Food (mix of self-catering and eating out) | £450-£700 |
| Attractions and parking | £200-£350 |
| Snacks, coffee, roadside stops | £80-£150 |
| Unexpected stuff (the milkshake, a lost charger) | £50-£100 |
That last line is not a joke. Budget for the unexpected. It always comes.
If you're weighing up whether a trip like this is affordable at all, it's worth running your numbers against what you'd spend staying home. There's a free salary and cost-of-living calculator that's genuinely useful for this, especially if you're comparing a UK road trip against something further afield.
The stops matter more than the destinations
For years I planned trips around places. Now I plan them around stops. A good stop is somewhere with space to run, a toilet that isn't grim, and ideally a bench. That's it. That's the whole criteria.
National Trust gardens are good for this if you're in the UK, though entry adds up. So are most country parks. So is any beach, even a cold one. What does not work is a "quick stop" at a petrol station with a single toilet and a queue of eight people.
We now plan a proper stop every two hours minimum, and we build in one long stop in the middle of each driving day. It adds time. It saves the trip.
Honest pros and cons
The good bits: You see places you'd never see otherwise. You're on your own schedule. Kids get genuinely better at long journeys with practice. It's cheaper than flying a family of four anywhere, by a wide margin. And there's something about being in a car together that produces conversations you don't get at home.
The bad bits: It's tiring. The driving is on you, always. Someone will get car sick. Someone will cry about something that seems absurd. You will spend more time than you'd like in service stations. And if you're the only driver, you need to be honest with yourself about how many hours you can actually do safely in a day. For me it's five, and four is better.
What I would do differently
-
Book accommodation earlier. We left it late on one trip and ended up in a place that was fine but forty minutes from where we wanted to be. That forty minutes, twice a day, added up to hours.
-
Stop trying to see everything. Three destinations in twelve days was too many. Two would have been better. Fewer places, more time.
-
Pack less. We used maybe half of what we brought. Kids wear the same three things on repeat. Bring a washing bag, not a wardrobe.
-
Buy the car sick tablets before you leave, not at the pharmacy in a panic. Ask a pharmacist what's suitable for your child's age. Don't guess.
-
Have one no-driving day per week. We skipped this on our second trip and by day nine everyone was miserable. A day where the car doesn't move is not wasted time.
If you're thinking about a bigger move, not just a holiday, the same instinct applies: fewer assumptions, more checking. The city and country comparison tool is a decent place to start if you're weighing up somewhere new.
Quick practical tips
- Keep a plastic bag for rubbish within reach of the front seat. It stops the car turning into a bin.
- Pack a small first aid kit with plasters, paracetamol for adults, and rehydration sachets. You will need one of these things.
- Take a photo of your parking spot every time. Every single time. This has saved me more than once.
- Bring more water than you think you need and fewer toys than you think you need.
- If you're crossing borders, check what documents kids need well in advance. Some countries require extra paperwork for children travelling with one parent.
FAQ
How long should a driving day be with young kids? For kids under six, I'd say four hours maximum, split into two or three legs. Older kids can handle five or six. Anyone who tells you eight hours with a toddler is fine has either never done it or has blocked it out.
Is it worth doing a road trip with a baby? It's doable but slower. You'll stop more, and you'll need to think about feeds, naps and shade. The payoff is that babies are portable and don't argue about the playlist.
What's the single best thing to bring? A sense of humour and a spare charging cable. The cable is more practical, the humour is more necessary.
Should we book everything in advance? Book your beds in advance. Leave everything else loose. The best parts of our trips were the unplanned stops, and you can't have those if every hour is scheduled.
We're planning another one for next spring. Same route, roughly, but fewer stops and a better snack bag. My daughter is six now, so the milkshake situation should be marginally improved.
