interestingly I put this in Google maps - driving Faro to my house is 26 hours; adding a stop in Geneva only adds one hour.
Do you live in the Algarve or in the UK? I just wondered how this ends up being a one-way trip. Perhaps you’re taking a car-ferry to Portugal for a week’s holiday then contemplating driving home?
I have done numerous road trips but aways starting in the UK. DS aged 4+ copes fine with longer drives - but this is child specific. You know your kids best.
My tips are:
I always had an adult in the back seat and I consider this essential for a long trip (my oldest dd sits in the front and handles tolls + she is independent getting snacks and entertains herself). You won’t have that luxury. I personally wouldn’t want two young kids in a back seat alone for five+ hours … the squabbling!
If one day involves a 5 to 7 hour drive, the next day better be no driving or a short drive (an hour or two) to somewhere fabulous eg a theme park. On the homeward leg we will drive up to 8 hours but there have to be several stops to move and wee.
You have to accept there will be VAST amounts of screen time.
You need a comfortable roomy car and nothing much in the back seat except a few cushions and a bag of snacks and entertainment.
We have done total driving of 24 hours on holiday before (to and from UK). We always stop overnight somewhere nice, rarely just a roadside hotel - we pick local towns which I research carefully. Once we are in locations for several days, we don’t use the car at all, or minimally (supermarket run for self catered accommodation).
All our road trips are planned meticulously - I don’t leave anything to chance in the short stops. I know what hotel, what restaurant, even what play park we can visit so there is no faffing around. This makes all our stops very easy to manage and the kids aren’t restless and bored.
All our road trips are entirely child-centric. We looks for things to do on the way we know they will love.
