Our experience ~
We love POR, the theme pool is fun, and if she is a good swimmer she can hang by the "adult" end as our kids call it. Alittle deeper but quieter. Beautiful and peaceful resort. While the food court is large, it is not too loud and we liked it. Very nice quiet pools.
POFQ ~ we have never stayed but ate at and walked around. It is very peaceful and quiet, smaller resort. Food court smaller but sufficient. The pool was not crowded, but I don't believe it has quiet pools. You have the advantage of using any amenties at POR and the boat to DTD.
The only disadvantage to these two we found is if you have to use the buses they can get crowded, and that could be a problem for my child. We always got on the bus, but sometimes people that close to him is upsetting.
CSR ~ great resort. We found that while it is large and for conventions it was much quieter all over, especially the pool area, because so many guests are at the convention. GREAT theme pool. The pool is large and lots of seating with a super slide. We practically had it to ourselves. We enjoyed the Pepper Market, a "high end" food court, found it to be more of a sit down atmosphere. Food right at pool too. Also very nice quiet pools. Transportation was great.
Stayed at CBR and would not return. Theme pool was way too small and crowded. Very overwhelming for my child. They didn't want to do the quiet pools there. Food court was also too loud for him.
