Hi Melissa,
The Caribbean Beach Resort is beautiful!
It's such a sprawling resort that it's difficult to be close to everything. If you book a preferred room (they cost a bit more), then you'll be closer to Old Port Royale where the food court, pool, and gift shop are located.
If you did not book a preferred room, then I have a suggestion for you based on my personal experience at this resort. I recommend Jamaica buildings43, 44, 45, and 46 as they are close to the bridge that takes you over to Old Port Royale. There is also a quiet pool and bus stop nearby.
While requests are not guaranteed, I would have the above locations noted on your reservation. Another tactic you could use is to just have noted that you wish to be as close as possible to the food court, pool, and/or bus stop and list them in order of preference.
Here is

Enjoy!
