They have "tube" relay races, tie dying tee shirts, pool basketball games, water balloon toss, volleyball games, dive-in movies on Fridays. Something new this year is "black light volleyball" - a glow in the dark volley ball game. The games are actually offered to kids age 15+ (at a fee of $25 per team) - if there are no takers, then they allow kids 12+ to use the court at no charge. They also have henna tatoos poolside this year too - at a fee, of course.
Hope this helps.
