@bmillerick We're so sorry to hear of your setback and going back to the drawing boards when it comes to THE place for your wedding ceremony and reception. Conversely, we completely understand your need and desire to feel the magic when it comes to a decision, and going with your gut on this decision makes perfect sense.
We have had the pleasure of photographing weddings at Adults Only, All-Inclusive locations in and around the Riviera Maya of Mexico, and would be more than happy to offer some suggestions based on our experiences.
There is an adults-only portion with Grand Palladium, called the Royal Suites Yucatan. We were fortunate enough to photograph a couple there on their honeymoon, as well as be part of a wedding where the couple, in their mid-30s, had no desire to include kids in the background of their photos. She also wanted to wear heels and was adamant not to have her wedding with a beach setting, and Grand Palladium had a variation of options to choose from.
Another great option would be Secrets Silversands or Secrets Maroma. While we haven't photographed a wedding there, we did have family visiting at Secrets Silversands and went to spend 2 days with them with day passes. It was so refreshing being away from kid zones and we loved the fact that all the staff was focused on ensuring the adults were enjoying themselves, with drinks, food or activities, but without the need to focus on keeping children pleased with constant activities.
Hope this helps! We'll leave some inspiration from a variety of our portfolio, including photos from the couple who wanted an adults-only experience at Grand Palladium.
