No man you'll be fine. My GTI is lowered so it just is totally the wrong vehicle to take out there. Even someone with something like a Subaru Impreza would be fine.
The only area that's a little dodgy is called Slab City and there is some parts of deep sand out there.
GTI! Love that car.. And the people that need rides don't really live all that close to each other. (Huntington Beach, Arcadia, etc) How are we going to make that work? o.o
