You might want to post this question on the resorts page. I was wondering the same thing and the consensus seems to be all over the board. You have to take into consideration:
1. How much do you want to spend? Value, Moderate, or Deluxe?
2. What kind of theming do you like?
3. What parks do you want to be close to?
4. How many people will be in the room?
5. How much time are you going to spend at the resort?
6. What are the ages of the children? Are you bringing children?
7. Is the pool area a main concern?
And many more...
We are leaving in 5 days and decided to try out the new Pop Century for a couple of days and then switch over to CBR for the remaining 5 days. We have always wanted to go to CBR and we love the Caribbean - been there too many times to count. We have a DS (3) and a DD (8 months), so we wanted a nice pool area, but since it will probably be too cold to do a lot of swimming, it wasn't our #1 concern. The YC/BC pool is supposed to be the best (Stormalong Bay).
Good luck in choosing!
