There are several Riu properties in the area and while Riu Palace gives you access to all of them, it seems as though Riu Cancun was the best. My friends staying at Riu Palace said it was much more mature (i.e. reading books by the pool, quiet nights in, fewer young adults). Riu Caribe hosts pool parties all Riu guest can attend, but it's quite a bit away from the Cancun, non-resort night-life and shops. If you're looking to party, eat good food, have some entertainment for people of ALL ages, and be only a 10 minute walk from the Cancun nightlife, this is the hotel to choose!
