We have stayed in 3 of the 4 but have used the 4th amenities.
CBR - They have double beds, there are pirate themed rooms ( upcharge for these rooms, ) The have what we think is the best themed pool, who doesn't loves pirates !!! They also have quite pool which is a nice choice for relaxing. There food court is good and has lots to choose from and lots of space for eating. Also there is a TS restaurant on site, we have not eaten here in years, so really can't speak to how it is now.
Large resorts, with lots of bus stop but also they have a internal bus. That just makes the loop. We love the court yards with seating, nice place to grab a quick breakfast or cocktail in the evenings. Have stayed here several times, and would so again.
CSR - Queen size beds, This is a convention hotel, and does have that feel. Just not as Disney as we like, The pool area is nice, a bit spread out, the slide here is great. Food court we would consider this our least favorite as the options are not to our liking. Large resort, not our favorite lay out.
POFQ - This is our favorite mod. We just love everything about this resorts, The food court is our favorite for resorts, lots of choice we really love. Pool is nice, it is spread out with seating though. Boat to DTD, is wonderful and offer a nice evening, and other dinning options. Queen beds here, we love to stay facing the river, and enjoy strolling over to POR - one bus stop easy to get to. Very small resort compared to the others.
POR - We have never stayed here, but have used the pool Ole man Island and food court both wonderful and have used the boat to DTD and back POFQ.
Hope this helps
