Chelsea, there are tons of brides here that have gotten married, or are getting married, in various places in Mexico (and quickly expanding to other areas). If you let us know your likes and dislikes we can help point you in the right direction.
Definitely steer clear of Destinationweddings.com and those large internet "destination" wedding planners. Many brides on this forum have started out with those companies and later fired them, or at the minimum found them to be unhelpful.
Tammy, the host on this forum is a travel agent and is arranging the travel for my guests, as well as many other brides on this forum. Once you narrow down a location, she can help you with the accomodations.
Good luck with your planning and let us know how else we can helP!
