Lotte - crystal palace is great, that's,where we stayed when I did VLM. Pitches aren't massive, but being out of season should be fine. Train was pretty quick, straight onto jubilee line. One bit of advice though, go down to the a30?) going in, we,went via Richmond and Wandsworth I think, was a nightmare towing a van!
Caro - we've done the Vendee via Boulogne (they don't do that crossing now) was two days of hard driving, wouldn't recommend it. Know of a great campsite/b and b close to Caen/Cherbourg. Have you checked the day crossings? Often much cheaper.
School hols - it's a tough one. We're no longer allowed to authorise holidays in term time by order of Welsh Government. For a couple of days they could,be ill, but some families really take the Michael...
We used to drive to the Algarve (Western) every year, why?????
Think we pay about ??500 for the Roscoff crossing, but tolls are about ??50 + each way, the extra we'd do an extra 600 miles + each way, so costs about ??380 for us in the car alone and then there's the ferry crossing!
Good run tonight, Garmin ran out of battery so ran how I felt, rather than what the watch told me! Sub 10mm for lsr which I was pleased with. On top of digging over most of the allotment it's been a productive day!
