I wish I could make it down to Cocco Beach, but alas, its a 10 hour drive. Have fun on the beach. I've been there several times and stayed before hopping on a cruise ship at Port Canaveral. Don't forget to stop by Ron Jon's surf shop and get a tee shirt before you leave
If you have a day or so after the festival swing by Orlando and watch Terminator 3-D and the Adventures of Spiderman (3d motion ride) ride @ Universal Studios. It shouldn't be too crowded right now. Those attractions are what got me interested in Stereo3D. I think they've added a Shrek 4-D ride too since last time i went (5 years ago).
