We love POR. Our 7 year old son and 3.5 year old daughter also love the resort. It has a nice pool and you also have the option of going over to POFQ and using the Dragon pool. The Alligator Bayou section has trundle beds which are great for the kids. We also like the onsite restaurant, Boatrights, and prefer the POR food court over the CSR food court.
CSR, however, is also a great resort. We give it higher marks on bus service than POR. The main pool is more enticing to kids than the main pool at POR. The restaurant at CSR is wonderful, but not as kid friendly as Boatrights.
You can't go wrong with either one.
