Kathleen,
We did the land and sea in 2000, and stayed at the CBR. However, we made a special request to have a certain room, as it was the same room we honeymooned in in 1992. I truly love the Jamaica section. Our room was right next to the bus pickup, right next to the bus entrance, so you are the first dropped off at night, and first picked up in the morning. Very nice!
One quick cavet: The land and sea is something we won't do again. There just was too little time on land and on sea. You cannot do Disneyworld in 4 days. Not if you want to do it right. That's one day per park, leaving out the water parks, downtown disney, disneyquest (which we loved, although we would have never guessed). Once we got on the boat, we were completely exhausted. And 3 days at sea are not enough! In the future, we will do either 7 day sea or 7 day land.
I hope you enjoy the Caribbean Beach Resort. It is truly a wonderful Disney memory for my wife and I!
