I'm getting married on AC on April 2. I am also planning a very small intimate affair. I have gotten a lot of help from Iraida at belizeweddings.com. Even though we're only going to have 6 guests, she is helping me with the paperwork, ideas, reservations, etc. Drop her an email.
Also, use the search function on this board and look for weddings. There is A LOT of information, i.e. photos, ideas, questions, answers and comments.
