Congrats and to the forum! That's a tricky question to answer only because there are SOOO many variables that will go into your cost factor. For example, are you doing a private dinner that you have to pay per person, depending on the resort you choose they have differences in price for wedding packages, decorations, do you plan on hiring a dj, photographer, etc.
We all have a different vision of what the "perfect" wedding is, so it becomes really difficult to compare. I know that doesn't exactly help you, but hopefully it will help you narrow down your questions. Good luck!!
