It really depends on how much time you plan on spending in your room. (We never made into the room until well after midnight and back out again at 8 or 9AM) All of these places are on the beach. I just returned last Monday having spent the entire week at Seven Seas, with no regrets. The grounds are beautiful and the staff is superb! Plus the price allowed me to get my fill of lobster!
I did find the beach area around Banana Beach and Mata Rocks a little more to my liking, and the Squirrels Nest is a neat little place...but my fave place to hang out was BC's.
I haven't heard a bad thing about any of the places on your list. The Palms is probably the most central of the ones on your list. Banana Beach will require some walking, or a bike/golf cart. Good luck and have fun. Be sure to go see Tony and Yvonne at Fido's dock for Parasailing or whatever, Tony can hook you up! AND DON'T MISS BC'S BEACH BBQ ON SUNDAY!!! LIP SMACKIN'GOOD! Tell Charlene the Pirate said HI!

P.S. I was de-stressed the minute I set foot on Belizean soil!
