KCNBT-
Well, I'm mostly looking at the Riviera Maya now- I like the ease of getting to Cancun, but Cancun seems so commercialized, and, as silly as this may sound- I'd really like to do a trash the dress session at one of the ruins w/ cenotes and such, but I don't want that to be a 2 hour drive (one way) from the resort we are staying at- talk about a long day! So right now the only Cancun resort I'm thinking about is Dreams Cancun, and they fill up quick on dates, so I don't know!
I'm looking at the Barcelo resorts in Puerto Aventuras quite intensely at the moment, as well as the Catalonia Riviera Maya (though their rooms don't look quite as nice). I am also thinking about the Dreams Puerto Aventuras that will be opening later this year. I'm leery since it hasn't opened yet, but I've heard nothing but good things about the Dreams resorts, and their beach looks nice, so we'll see. Good luck!
