Hi Chelle, welcome to the forum and congrats on your upcoming wedding. The good thing is that in most cases DW's can be planned in a few short months. We have some great travel agents on the forum that can work with you on you and your families budget, once you have a location down, I'd book the vendors that book up quickly, IE resort and photographer.
This is a great forum with a ton of useful information on it. I' am sure you'll love it here, I was a destination bride as well, and this forum was a huge help.
