I walked past it when I was in Xcalacoco in December. It's just next to the Princess when you go toward Cancun walking on the Beach. It was still in construction, but it was getting close to the finish line. First thing you have to know, it's HUGE ! It took us like 10 minutes to walk from on end to the other. We were joking about people that would get a room on one end of the resort, and would have to go the other end for whatever reason. Like, shoot ! I forgot my jacket in the beachfront restaurant ! and there you go for 10 min
When we were there there were some big sandbags (or ??) in the water, I think they are trying to build up a beach with sand in the water because the whole are is pretty rocky.
It's made of big buildings that are 3 stories high. Each appartment is built in such a way that they have a terrace facing the sea with open air - like, the terrace above you would be farther away, in the back, you can actually see it in the pics on their website.
Other than this, I don't know ! One thing, it's more 10-15 min away from Playa del Carmen than the announced 5 min on their site. It's still close, though.
