We just completed a 10 night stay at the Marriott Casa Magna. This is our third trip to Cancun in the last 12 years but the best resort . Hotel was not very crowded this time of the year so no waits. The staff was very friendly and helpful. Our ocean view room was spacious and well equiped. We included the breakfast buffet with our stay and it was wonderful. There are pilapas on the beautiful white sand beach and most days the ocean was calm enough to enter. ( We live on the east coast so the waves are not a problem ). Between the Marriot Casa Magna and the JW Marriott which are connected there are 6 resturants at night or you can catch the bus to go anywhere along the Hotel Zone and downtown Cancun in front of the hotel. Aqua Water Sports is a 10 minute walk and you can purchase your activities at the pool . We have used Aqua in the past and on this trip. 7 Eleven, and a 24 hr market (snacks, drinks ,beer and liquor) and McDonaldsons across the street. I cannot say anything negative about this property and look forward to returning.
