First time in Fontainebleau

Hi everybody!  I am going alone to Fontainebleau this weekend at 4-5 April, or maybe at the next one at 11-12 April. I'd appreciate if you can give some advices. I am planing to stay at camping and move between the spot by my feet. I don't know exactly what level i have, but its approximately 6a-6b. Also i am looking a company of climbers for a climbing together, and to have some fun.  Cheers! Yaroslav
