Hi L.,
We don't have experience specifically with the summer camp, but my 2.5 year old goes to Pee Wee Club and he LLLLLOOOOVVES it! Not only do they do all the typical pre-school/play-school types of things, they also take the kids swimming at the end of each 3.5 hour session. He only goes once a week, but he would happily go more. They also do yoga and lots of other physical stuff.
Several of my friends have had their kids do the camps and have been really happy. I think I put my older kids in a couple days last year, but not enough to really get a good flavor. The signs they put up say that they've made some improvements, so that's good. I think that means they listen to the parents about concerns. I do know they spend some outside time out on the roof deck and they go swimming everyday in the 4th floor pool. I would say, if it's like their other kids programs, it's probably pretty good and reliable. I haven't asked in the past, but with camp I would definately ask if their councilors have been "background checked". Unfortunately, we need to be asking this at all the fun activities we have our kids do, although it's often uncomfortable. Still, our kids are our most important assets! Good luck! J.
