First trip to the Riviera Maya area. I have stayed at both the royal mayan and royal islander in cancun on prior visits. What is available to choose from is a 1br at the GM vs a 2 br at the MP. I would really like the extra room but have read the GM is newer/nicer. Although I have read the pool is bigger at the MP. Does either have a lazy river yet? specifically if I stay at the MP what will I be excluded from using? thank-you so much, Dawn
