I've been to all three over the course of a few years -- from my memory the CSR has the longest slide. It twists and turns a few times and goes under a jaguar that spits water at you. POR has the second-longest, and I don't remember it being quite as steep and fast as the one at CSR but it's still pretty fast. It winds through trees and bushes so it's kind of hidden in all the photos I've seen. The slide at CBR is pretty short, as it is contained in the "fort." POFQ is very cool looking but not very steep/fast so it is good for younger kids. We'll be staying at POFQ in May and I'm planning on taking my 2yo to the pool/slide there and letting my DH take the two older kids to the bigger slide at POR.
