My husband and I have been to many All-Inclusive, adult only resorts in Cancun and Riviera Maya areas.
Secrets Maroma was our absolute favorite and we actually got married there 6 years ago this December.
It has one of the top 10 most beautiful beaches in the world and we had no complaints about any of the restaurants or bars/lounges. A few of the pools are heated but the weather was great in December. If your budget allows I would upgrade to a swim out room or ocean front room. We've had the preferred club for all of our stays there.
Another option could be the newer Secrets Akumal, from everything I've heard it's similar to Maroma if not better.
We went to Excellence Playa Mujeres in July and we loved it too. Secrets Maroma holds a special place in our hearts but I would send anyone to EPM any day. The restaurants were all amazing including their Lobster House where it's all you can eat lobster all the time. The seaweed has been bad this past year and it was definitely present at EPM. Not sure about the Secrets properties, I'd have to check.
I've heard some good things about El Dorado Casitas, Secrets Playa Mujeres, & Breathless Riviera as well.
I'd be happy to answer any other questions and/or send you some quotes!
