When I saw the pictures, I did some research about the beach. I guess the government had some problems with the resort and their way of creating/preserving the beach (stealing sand?). I read an article that basically said 1)there were unsolved legal issues with the resort and govt 2) the resort was last on the list for beach rebuilding due to legal issues 3)the resort's owners were being stubborn and 4) the beaches were being rebuilt as of late 2009 but they skipped the Real Resorts (both).
I THINK the issues were resolved and the beach recreated but I am not sure. The person who posted the article link made a vague statement about the entire beach repair (all of Cancun) would be completed before February 2010.
