The resort is not even close to being completed. The main pool is done. It is huge and is one of the largest in Mexico, but the service by the pool was the worst. We waited at times an hour for a drink. They are under-staffed and do not speak English well.
We were at the Grand Mayan and the rooms were great but far from everything else. We had a 2 bedroom that slept 8, IMO it can sleep 14. There are no Ocean views because of the way they are built. This is to prevent hurricane damage.
Some things about the Italian Restaurant were amazing. The Italian Restaurant has an unbelieveable atmosphere. The view of the pool from above, all lit up at night, was amazing. There is also a cigar bar in the rear. But because of a forgetful waiter, our night here was ruined. He forgot one entree and never brought the vegetables that came with the meals.
Right now they have 700 rooms. When finished they will have 4000 rooms. The Spa is almost up and should be done shortly. Where ever you walk you see and hear the construction. In a few months all of the Grand Mayan units will be done as well as the mini rivers on the resort, but I do not think the other half of the resort will be completed too soon. Whatever is done already has made it a huge resort. But poor transportaion to get around. Parking is very far away. You may need a cab after parking if you're lucky enough to get a spot. The resort sprays for bugs nightly and does not notify you, so you may get a mist of insect spray at any time.
For the kids they did have a a lot of pretty good activites by the pool.
If you want location then there are 2 sides to how you look at this resort. If you want a party place with lots of restaurants and great beachs, then stick to the Cancun Area.
But if you want to relax The Mayan Palace is the place.
One further note.
Even if it seems the Mayan Palace is in the middle of nowhere it is close to Tulum, Xcaret, X-Ha and it is by Playa del Carmin, which has a ferry that will bring you into Cozamel. It is also close to Puerto Moralas which is a small fishermans village. It would be cheaper to rent a car and use it from the MP and go to these areas from the MP, rather than using a tour from Cancun.
As far as a tip goes, get UP REALY EARLY LIKE 6AM. Go to the pool area and get one of the large king beds that are under the palapas. It was so comfortable that you will feel like a king.
