Are we mad driving Calais to dordogne... No stop overs? HELP !

[Hattieboo]

Mumsnet has become very helpful in persuading my dh to come round to the right way of thinking! We're off to France in caravan with dd's (5 and 9) on Thursday. Ferry is at 11pm ish, and dh thinks we should get to Calais and drive drive drive! I can't tow the caravan so it will just be him, and I'm worrying :-( we have our campsite (for 12 days) from Saturday night so we do have to sleep somewhere on Friday, but we were hoping to get as much travelling done on Friday... Hopefuly not as busy as Saturday? He suggested sleeping some where near Calais on side of road! IS THIS SAFE and legal??
Any suggestions MOST welcome!!! X

When we go to France we drive down to Dover on day 1, get the ferry across and stay in a hotel, then on day 2 we drive from Dover to down to past Toulouse - it takes about 11 hours including breaks and DH is the only one who can drive. He seems to quite enjoy it the wierdo

We're going to Les Penyrals near Salignac which is about a 10 minute drive from Sarlat. We've been there 5 times before ,it's a lovely site, not too big but with fantastic pools and a nice restaurant and bar. I can't wait.
