Have stayed at both more than once and have kids. Both have great themes, just different. Both have offered us excellent customer service. Both have always been very clean. We consider both very easy to navigate.
I would rank them equally. When my kids were younger POR was great and I would still go back there!!! Now that they are teen and pre-teen, they really enjoy CSR more - because of the pool/area.
Both pools are good but the slide on the CSR is bigger so they like that. I think there is also the advantage of much more seating, some under cover at CSR pool. Both playgrounds are nice, but if your child is still very young CSR is more manageable. I found the POR was for older toddlers and up. We had a toddler at CSR and I liked that the kiddie pool was close to the end of the slide and I could watch everyone. We liked the options at the CSR pool "food" bar ,but haven't tried that at POR in a long time.
We love the food court at POR but if you want something with alittle more service and variety, then CSR is good too. If you like sitdown, the POR may be more reasonable, we thought CSR was high, but it is there to cater to convention people.
Both have good recreation amenities but POR has boat to DTD if that is something you would use.
There truly are pluses at each, and I think it just depends on what theme you would like and if there is something particular that is important to you. You enjoy both equally. As you can see we have stayed at CBR and have no plans to ever return there.
