Just back from the trip and HD a great time. Thanks for all the tips. If anyone is in a similar situation in the future, hope anybof this helps.
Over Easter weekend the place was pretty busy, but it was easy enough to escape the massive crowds. As long as you're OK with sharing the place with a few others, I don't think it was a problem. Sabots, 95.2, isatis and cuvier were the only properly busy places we found.
JA Martin was great, the orange cirvuit looked superb and enough 7s to keep me happy. Some of the better hard stuff is in the sun though.
Cuisiniere, whilst busy, felt OK. Again, great oranges and the harder stuff there blew my mind.
Franchard hautes-plaines was a nice slightly more off the beaten track venue. Not loads of good 7's,but enough for a day. Wish I'd found the bloc.fr problem earlier in the day. I wandered over to isatis and it was absolutely rammed whilst we had hautes-plaines in peace and quiet.
On the last day we stumbled across restant de long rocher, just because it was the nearest venue to where we were staying. I had the Red circuit to myself, which is a really good circuit. A bunch of good looking 7's and good looking blue and orange circuit too
We will be back
