We have stayed at POR, CBR and CSR. We'll probably stick with mods, so I can't tell you about WL. There are too many other things we'd like to spend our money on than a deluxe(like maybe another trip someplace!).
Someone mentioned movies in the evenings. I think all the resorts have movies now.
We just got back from CSR and really enjoyed it. They do have hammocks, although not as many as CBR. The pool was really great. THe slide is longer than the other slides by about 25-30 feet. It was easy to see the kids wherever they were in the pool. The hot tub is really big there. They also had a ping pong table, volleyball court, the arcade, bar and snack bar by the pool. The only downside to CSR was that those things are all pretty far away from the main building where most of the food choices are. CSR had the most food choices of all the Mods we have stayed at. We also really liked the quiet pool in the Casitas and the health club.
The beds had duvet covers on them and they had nicer toiletries than the other mods we had been to. That really added to a deluxe feel to things.
POR has a really great atmosphere and the boat to DTD is nice. There is a bit more shade around the pool area at POR, which is a huge plus for us. I thought the food was better at POR and CSR than at CBR.
I think it's a tie with POR and CSR for me as far as which one I like the best. CSR is probably edging out POR though.
