Hi,
You are right, big resorts are wedding factories. I’ve been at the Barcelo Maya Resort with 7 wedding the same day! Can you believe that!
May be you can contact an independent wedding coordinator able to propose you different options. I know Weddings Riviera Maya.
About Moon Palace: I shot a wedding there a few weeks ago. Kalena, the wedding coordinator is very sweet and professional. The resort has an amazing beach and very nice location for the reception.
