If you're looking for the best swimming pool in Las Vegas, The Beach at Mandalay Bay doesn't disappoint. It's the main reason why I booked my stay here this time around. \n\nPools are open from 9am-5pm (seasonally) and gets crowded fast. So make sure you get there a little before 9am (some lined up at 8am..) to ensure the best (beach chair) spot.\n\nThe room showed a bit of wear and our two queen beds weren't comfortable due to the lack of support. Aging must have taken quite a toll since my last visit. Checking-in was friendly even at midnight, and housekeeping is quick to bring up whatever you've requested.
