Here is the response that I received from the hotel. Looks like they just expanded on what others have already said. It also looks as if the construction will not be as much of a problem as I had anticipated. For a deal like this, I think I will book. Would be nice to see what the above poster's travel agent thought of the resort.............................

"The first hotel the Grand Sirenis Riviera Maya has a circular shape looking at the beach. In the middle of the circle there is a big garden with plants, and one of the swimming pool with the pool bar and on one side the steak house restaurant. So when you cross these facilities there is the beach. That means 5 minutes walking.
Beach and swimming pools area are equiped with sun beds and palapas and pool/beach towers are included and you can change it each day.
In about one month we are ready to open the first Hotel Grand Sirenis Riviera Maya, meanwhile we are already built the blocks of rooms of the second Hotel. That means that while the frst hotel is open, the building works of the second hotel will be minimum, because it is just matter of details inside the block.
On the other side, the second hotel is not so closed to the first one, but they share the same facilities.
The third and the forth hotels will be build about 2 km away from the first two hotels, and we are working just on the plans at the moment, the opening of these two hotels maybe 2008."
