We went last year on August 24 to be exact (it was my daugher's 7th birthday). We purchased our tickets early in the day, so we didn't have to wait in line. There was burgers, dogs, corn, fruit, chicken, cornbread, and some other things I can't remember at the moment. Also, lemonade and iced tea. We ate early, and then there were patriotic arts/crafts and face painting. I believe my girls made a necklace out of red/white/blue wooden beads, a sparkly red/white/blue pin to wear, and something else. Then, there was a DJ by the pool playing fun music and doing silly things with the kids, they announced my daughter's birthday, and had everyone sing Happy Birthday, then had her lead the conga line around the pool to "Hot, Hot, Hot". We danced with the kids for a bit and before you knew it, the fireworks over the marsh had started. We had a ball, and will be there the same week this year and will definately do it again.
Price I think was $25 or so for adults, maybe $15 for the kids. The crafts were $1 each.
