I was wondering if anyone has stayed in either of the Riu Palaces (Mexico/Riviera Maya) and had guests who stayed in one of the other Rius (Tequila, Playacar, Yucatan, Lupita). I was looking to have my wedding at Riu Palace Mexico, and the price is okay - for us - but want to keep my guest budget down. If they can stay at the other resorts for less and we can all interact then I could theoretically have my cake and eat it too. So my question is, how much of a hassle is it for guests of the various Rius to interact? Can we visit each other's buffets/bars? I've heard that the Tequila is where all the other Rius go to party and I'm okay with that idea. Anyone with cross Riu experience?
