Do not stay at the Moon Palace, I stayed there in 99, it isn't hooked up to the Public water system(safe for drinking) and I got the worst case of the Runs ever. Water comes out green out of the spicket. Stay in Cancun, the Moon Palace really isn't in cancun. I've been to Cancun 3 times and that was the only time I ever had a problem and trust me, it made the week miserable.
