Would appreciate recommendations for all inclusives in this area. We are interested in visiting the ruins, but also having a nice resort vacation. Would love something with lots of activities but also somewhat "nature involved."

Since there's been some confusion on other posts regarding the term "Mexican Riviera", confirm if you're talking about the Pacific coast between Puerto Vallarta and Manzanillo, which is called the above and also is known as "Costa Alegre". But since you've mentioned seeing ruins, I think you may mean the "Mayan Riviera" which is the area on the Caribbean south of Cancun.

South of Cancun is what I would be interested in seeing.

Went to the Barcello Maya couple years ago. Great beach and pools. Had a fantastic time.

We have stayed at Iberostar Tucan Playa del Carmen and Bahia Principe Tulum. We highly recommend Iberostar. It had the best grounds we've ever experienced at the many resorts we've stayed at -- a miniature jungle with lots of monkeys and various other small wildlife (cross between a large guinea pig and a small pig). The rooms, restaurants and beaches were great too.
