I got married on AC two years ago. There are lots of wonderful places to get married there (and I have no commercial or other interest in any business on AC). I used Iraida at www.belizeweddings.com
to coordinate the minister, flowers, photog, etc. We stayed at and got married at the SunDiver (www.sundiverbeachresort.com
). It was the perfect wedding. We enjoyed the hotel a lot. We were the only people there (we had 16 guests), and they were very nice. Nice pool, nice beach, great staff, etc. They are north of the cut, so you have to take a boat in to town (which was the only draw-back for me).
There are lots of hotels that offer wedding packages. Go to the lodgings section and check out Victoria House, SunDiver, Ramon's, Mata Rocks, Mata Chica, Captain Morgan's, etc. Many hotels have a wedding special on their websites.
Good luck! Feel free to ask other questions. I loved getting married on AC and would not have done it another way.
OH - btw, Howdy for JJW's hometown of Austin.
