Corrine, I stayed at SunBreeze last May and it was great. You just walk across the tarmac and you are at the hotel! They will send someone over with a cart to bring your luggage if you want. Just ask the airline to call them. I stayed in room 225 - the best room in the place w/jacuzzi tub and a great view of the ocean. BCs BBQ is next door and is the place to go on Sunday's around Noon.
There are a lot of great places in AC depending on what you're really looking for. I know that I really was set on a pool which is why I selected SunBreeze. Of course, I only went into the pool once because I was so busy on day trips or mingling. So, now I am staying different places to experience more of AC.
No matter where you decide to stay - you will likely not be disappointed, or at least so many other great things will make up for what may seem lacking in accommodations.
You're gonna have a great time - you better Belize it! (31 days and counting!)
