Welcome Darlene! I don't have any friends who have gotten married there, but I have family members who recently went to a wedding their (a relative of theirs lives in that area). What I do know is that if your not going the resort wedding, and you are using local vendors, etc. it is very affordable. If your friend speaks spanish (I'm assuming she does) I'm sure she can ask around as to which vendors have a good reputation. If you want to know something specific I would be more than happy to ask my aunt if she could get the names of vendors that her niece used, etc. Hope some of this helps and good luck with the planning.
