I have stayed at the CSR - it is very pretty, southwest theme. My son loved the pool and we enjoyed the small poolside restaraunt. However, LONG walk to food court. I would take DS to room after park and DH would hike (we called him Pedro the pack mule!) to the food court to bring the dinner back to our room. More than once DS was sound asleep by the time he returned! Food Court was ok and well as the sit down restaraunt (can't remember the name) We are staying at POR in May (now with our 3 kids) Hoping for the best! Hope this helps you make a decision. All said, you always have fun in the World no matter which resort you choose. They are all magical!
Oh yeah, split that trip - stayed at the CBR- liked CSR MUCH better. Much less crowded and seemed cleaner. (I think it was fairly new at the time, maybe hadn't caught on yet).
