From what I've been told by someone at the Caribbean Beach (not just a castmember at the central call center), the resort rooms are going to be refurbed in 2014. Surely, they will be getting queen beds since they are the only moderate who still has full size beds. Someone on another forum posted pictures of what is believed to be a mock-up of the new rooms and they have a very tropical look to them using tans, brown, rattan, etc.
We have stayed at the CBR many many times and it's quite family friendly. The resort is centrally located so it doesn't take long to get to any Disney destination via the bus. The resort is large but it's not so large that you can't walk from any building to Old Port Royale which is where the food court, store, arcade, concierge desk, main pool and marina are located.
Each resort village has it's own white sand beach complete with hammocks and beach chairs. There are also laundry facilities and quiet pools in each village. Oh and a bus stop in each.
The main pool is zero entry and has two slides. Two hot tubs are near the main pool as is a kids' water play area. The pool bar is located near the main pool. This is also the area where they show nightly movies in the courtyard (weather permitting).
At night, you can see some of the higher Epcot fireworks, Illuminations, from several locations in the resort.
If you have any specific CBR questions, feel free to ask and I'll try and answer them as best I can. I have pictures of the resort in my trip report if you want to have a look around. The link is in my signature.
