Hi Morgan, welcome! I'm also from Texas and an "unofficial bride". I do know that my bf has bought the ring though, so we're sort of in the same boat - waiting. I live in Dallas, how about you?
We are planning on getting married in Playa del Carmen at one of the Iberostar resorts. The one in particular that we are thinking about is called Iberostar Tucan and it is nicknamed "The Jungle Hotel" because it surrounds an actual jungle with monkeys, parrots, etc! The beach there is supposed to be wonderful, and the prices affordable (It's AI as well, app. $850/person for 4 nights/5days INCLUDING airfare). Btw, if you are located near Dallas we found a great Travel Agent here that specializes in Destination Weddings - the agency is called Tiki Trips - Tiki Trips - Unique Vacations to Exotic Destinations. We're going to the Tucan in Playa for a site visit (before we're even engaged, ha!) June 9th-13th. Very excited!
Anyways again and let us know if you need anything!
