Any suggestions? Really want a premium beverage package and a premium beach to walk on and be able to swim in....not rocky. Thank you

Do you want adults only? What is your budget? There are hundreds of resorts in that area so we need more information in order to help you.

Secrets the Vine

Riviera Maya
Secrets Maroma
Zoetry

I've heard the Moon Palace is also meant to be an excellent property, although I haven't stayed there. Anyone have any first hand experience on that property?

The Moon Palace is a great property, sometimes over run by conventions, but it has a terrible beach. Terrible.

Barcelo palace. Great beach and get the club premium for upgraded everything. Or secrets maroma if adults only and get preferred club

Well, you haven't given us any more information.
If you want a luxury adults only on a great beach look into Royal Hideaway in the Playacar section. It is a rather quiet resort so if you want wild nightlife you won't find it there.

Sorry but I would rule out Barcelo due to their very small captive dolphin pool. They also limit the number of a la carte restaurants per stay unless you pay extra for their Palace section.
Really need more info though.

Stayed at Secrets the Vine last year and really enjoyed it. Food was good, staff very friendly and helpful, and the accommodations and hotel were very clean and modern. Would go back in a heartbeat.

Oh, and the beach at the property is fantastic as well.

No need to rule out the Barceló. It is a great property with amazing beaches and the ability to upgrade. All the hotels that don't have dolphin pools on their property sell them anyway and make a profit, so if you don't like that, I wouldn't go to the Mayan in general. Some Dreams have them which are part of the AMResot Groups, should we boycott them? Really ridiculous
