I've chosen to wait a couple weeks. We're planning on arriving on March 7th, and stay until the 11th in Cancun. Then we hope to travel East and down the coast to Playa del Carmen, and close to Tulum from the 11th-13th. So the 7-11th it will most likely be the Westin Resort and Spa (according to this forum), but trying to figure out what this other hotel is.
