They colored a pillow case and a drawstring bag, made a few misc. paper crafts, and made slime. Pretty much like the picture above. They also played games (my 8yo won a cap in some sort of dodgeball game), and they had video games (Mariokart maybe?). I made my 11yo go with his younger siblings the first time they went, and he liked it but he preferred Edge and didn't go back the other time they went. My 8yo (9 in a couple weeks) really enjoyed it- she loves crafts and games and is very much a people person. My younger son (5) also really liked it.
ETA- we put the younger two in Scuttles Cove on Castaway for a couple hours cause we wanted to see Serenity Bay. We felt guilty for taking them away from the beach, but they LOVED it. So much water, sand, and they made some sort of volcano with a hose. They were wet and sandy and very cheerful when we picked them up.
