hi roseanna,
i'm getting married at the yucatan in july. the moon palace is gorgeous! but i love the yucatan for its lushness and it's affordability. the number one thing in planning my wedding was making sure that everyone i want there would be there, so in my opinion, the riu yucatan is a great price for what you get. that being said, the wedding packages are not a bargain, i agree with you! but here's a thread with some pics and there's also information in there that i received from the wc.
