Wow. Thanks for your honest review. I was also looking at ME Cancun b/c I like the moderness of the hotel. But ME Cancun always seems like its a "Hot Spot" hotel with a Miami Style party vibe and All though I want people at my wedding to have a great time. I think having it at ME Cancun would take away a lot from my wedding or take the focus off my wedding and more on partying it up.
I've also read a lot of the TripAdvisor Reviews too and a lot of the visitors were not happy with the hotel are the All-Inclusive plan. Some complained too about the constant pressure to go to timeshare seminars, etc.
So again Thank you for your review. You have defintely helped me ruling out ME Cancun.
