I recently did a site visit to Cancun and visited both properties. I felt that the ERC was better suited for our wedding because of the ceremony and reception sites (there are more at ERC), the difference in the wedding coordinators, Gloria at ERC was fantastic, LLenny at PM totally forgot about our scheduled visit and wasn't even at the property. We had to wait about 40 min for her to arrive and then she rushed us through the property. She said no to almost every one of my requests (Gloria said yes or she woudl see how she could accomodate our needs). Llenny said there was a ballroom as a rain option but would not show it to me despite us standing just below where it was located. Also, the PM property was far more busy and the staff seemed like they were working just to keep up with the crowd. There was empty champagne glasses on the tables in the front check in area, etc. The staff at ERC was beyond friendly and made you feel like they truly loved where they worked and the place was immaculate. Honestly, this is just being nit-picky because I HAD to make a decision. Overall both properties are beautiful! The PM property is newer and definitely has a huge "wow" factor but ERC just felt right to me. I have pictures from both site visits if you would like to see please PM me your email and I will send them to you. You can't go wrong at either property but def. keep on top of LLenny (or ask for the new coordinator, Andrea, she was very sweet)
