I got MERSA while staying at Mandalay Bay so did my son who is 5. We were in the pool for 6 days and in rooms 32215 and 23334 wouldn't stay in these rooms until there cleaned really well and wouldn't go back in the pool unless I saw the water tests. I still haven't heard back from Mandalay Bay. Very poor customer service.\n\nJim Larson  \nTracy, CA
