We first decided on a location, and that took awhile but once we decided on the DR, we went to a travel agent, my best friend's sister. As she goes to the Carribean a lot, she gave us the scoop on a lot of resorts and helped us decide. When deciding where, there are lots of things you have to think about, if you are doing a civil ceremony and not a symbolic one, look into how long you have to be there before and if it requires you take a blood test (Mexico does). That will help you narrow down your choices. Also, check out the threads on the various islands and see what people are saying / issues they are running into. Above all - have fun with this!
