Well, my parents did actually buy a timeshare here. There are all kinds of timeshare pitches in Cancun, and this place does their part. If you buy a timeshare or even rent there on a daily rate, you won't be disappointed. It is centrally located in the Hotel Zone and has good amenities. They have a tour operator, pool, spa/massage, hammocks, private beach, and restaurants. They have large two-bedroom suites, the type of room we stayed in. It is large, with two large bedrooms, a large Jacuzzi tub, and views of the ocean and pool. The food is very good, but honestly, we mostly ate outside of the hotel.
The lobby area is a bit small and can get congested, especially when there is "lobby entertainment." The tennis court has been converted into a stage/amphitheater for variety shows and a dinging area.
It is easily accessible by bus or taxi, and we usually go for walks on the sidewalk in front of the hotel towards the downtown area.
This is a high-end hotel and good overall. As I said before, just beware of the timeshare salespeople unless you know you will use it and make the most out of it.
