I'm getting married at the Yucatan on January 11th. There are a few differences between Yucatan, Playacar and Tequila. Yucatan is newly renovated, on the beach it has the complex's fitness center and health club. Playacar is a little smaller, but older, on the beach. The bad thing about the Playacar is guests have to determine what time they are going to eat each night - like a cruise ship. They sign up for 6 pm and then they have to eat at that time every night, so not as much flexibility if you want to do a tour or something. Tequila is less expensive, but still nice, off the beach. You use the beach of the other properties. The Tequila has the disco and supposedly one of the best breakfast buffet's in the entire Yucatan. I chose a Riu because it was less expensive for the guests and close to PDC so we could get off site for activities. Dreams Tulum is also very nice, but it's more expensive and further out, so it'd be a very expensive cab ride if you wanted to go anywhere. If you stay at Dreams, you're more likely to spend the whole on site, which isn't a bad thing, you just need to consider that.
