We still haven't found a resort yet but this Saturday we are going to finally pick one. We started looking into resorts and prices and destinations in the summer. We are also over a year out from a wedding and you are right prices haven't changed too much.
I picked our resort primarily off of pictures of other weddings. That was the biggest help to me, because I could actually envision how our wedding would be and look. All of the wedding packages start to look the same after looking at about 3 resorts, so having a list of things that you really want is helpful also.
Can't wait to hear where you have chosen! Good luck!
