RIU Cancun is not as much of a "party resort" as Oasis was. But it is right next to the clubs and during the day we still find people to party with and have fun. Yes there are some families and older people, but there are still plenty of young people. The party is what you make of it. I like to stay in a bit nicer resort and then party hard in the clubs. RIU Palace is where you get the most older couples and older people in general. The cool thing is you are in CANCUN and it is awesome no matter what!!!!
