Welcome and Congrats from a fellow Aruban Bride! I'm getting married next July on Renaissance Island.
As far as location for your wedding- it all depends on what you would like for your special day. Also, the size of your group is important. do you want all inclusive or not?
A few places that I looked into were: Bucuti, Occidental, Marriot Stellaris, Riu, Manchebo, Radisson, Westin and of course the Renaissance. Each place is unique and you will have a different experience.
Let me know if I can help in any way.
