This sunny, seaside everything-you-want resort reigns as the first rockin' Riu to hit the shores in Mexico. And its prime location in sweet Playa del Carmen makes it a fan favorite, no doubt. Not only do you get one of the prettiest beaches out back, but you're also close to local shopping, restaurants and of course, three sister resorts, which means triple the fun. You can splash around in one of their pools and sample a cocktail or two. Riu Yucatan definitely delivers happiness. And then some.
