I live near Pismo and go there quite a bit you camp right in the sand !, Its gunna be tricky with 2 wheel drive but its doable! make sure you check a tide table and try to get there as close to low tide as possible !! very important , as it is easy to drive on the wet hard packed sand, after you pay and drive down the ramp pull over and air down to 10 lbs all 4 tires ! try to select a spot not to far from the ocean but far enough away that so the water dont swamp your camp at high tide . pick a spot a nd get a good run , and it really helps to stop on the hard pack and un load the toys first !
find a nieghbor at a near by camp with abig 4x4 and make a new friend share a few beers and cut a deal with him to help tow u to the hard pack if needed when it time to leave , dont worry there will be lots of peeps willing to help . and as far as the buggy goes I say take it . have fun
