We stayed in CBR last year (was just renovated) and LOVED IT! The kids loved the pirate pool and the casual theme. We stayed in a standard room with some minor Nemo theme to it, but there are also pirate-themed rooms that look really fun!
We were leaning toward CSR this year, but needed a 1/2 marathon hotel so it was out. THe new renovations, queen beds, and central air (v/s the wall units which can be loud) were big appeals. I believe I read that the pool is having some work done right now, so you might want to check and see when it will be done based on your trip.
I looked into POR for the marathon, but it has been a while since it was renovated. Some ppl have said the rooms are really showing their age while others say they are in good shape. Guess it depends on the room/building and how often it has been used over the years. The food options and boat to DTD looked great as did the possibility of a trundle bed since our kids do not sleep in the same bed well, lots of kicking, falling out, and screaming in the night.
Really, I think any choice you make you cannot go wrong. Have fun planing and a great time on the trip.
And you can always modify/change your resort. I have changed mine 8 times.
Picking a resort can be harder than it looks... think it might have been better before I found the DIS board and kept reading and reading and looking at pictures and second guessing myself.
