Hello,
There are so many options that you need to set-up priorities:
All inlcuse or not would be the first one...if you don't care about food than all-inclusive is ok...if food is a priority then avoid the all inclusive
Privacy - some hotels are wedding factories where you are just a number...."next bride, please!"
Budget: try to elaborate a budget and so you can narrow your choices
THis is just a start...then each hotel has its politics....and that is the next step....do I wan ttheir vendors, do they have more than one wedding per day.....
Lots of homeworks!
