Classic VW Campervan
There seems to be good availability from SunHatFrance who have recently bought two retro VW Campers* to hire out for self-drive holidays. We used the company years ago and self-catered in their holiday home in Provence so we're thinking about exploring a little further around the South of France, without having to plan too far ahead or panicking about booking hotels and paying extortionate rates.
Verdon Gorge, Provence
For example, a photo on the SunHat website shows the Verdon Gorge - which looks amazing - but we've never been there! They also wax lyrical about other places, such as Aix-en-Provence, which I'm also desperate to visit. I'm sure they won't mind that I've 'borrowed' a couple of photos from their website.
The newly refurbished campervans are said to sleep 4 so we expect it to be better for just two of us, with plenty of storage for clothing and food supplies. Cost-wise, it's similar to a 3* hotel but you save on not having to eat out every night and paying €25 for a bottle wine that costs €5 in the supermarché. Flights can actually be cheaper than petrol + motorway tolls and will take far less time, especially if you have to start your journey from the North of England/Wales or Scotland. MPG (or LPK) may be dearer - not sure - will have to ask.
It sounds quite exciting just writing about it! My parents had an old VW caravanette and it was really easy to drive, once you got used to the fact that there was no bonnet in front of your face! Here is the link if you want to explore the idea: campervan holiday in the French Riviera.
*No longer available to hire but static caravans for family holiays are.
