Welcome to the forum Cher! Maybe you could start with a preliminary planning session and set out your budget, your wants (all-inclusive or not, mega resort v. small hidden gem, beach ceremony v. gazebo v. indoor), and a draft guest list. Try to pick a couple of places to research further to determine prices for both you and your guests, the weather, etc., and try to figure out who on your guest list is more likely to miss out. You could have a great AHR in Vegas, you’ve got some of the best restaurants at your finger tips (IMO).
Good luck and happy planning!
