Review for Resorts World Bimini Bahamas Resort, Casino & Marina Review For Park MGM Google User Oct 28 '17 at 21:03 The check-in time here is 3pm. I arrived to the hotel a bit early, but they gave me the hotel room key cards. When the rooms are available, they will text me with the room number. In the meantime, we have access to the pools at MGM and Mandalay Bay (just show them the room key card) since the pool in Monte Carlo is being renovated. We took the free shuttle bus from Monte Carlo to Mandalay Bay which comes by every hour. Nothing better to kill some time waiting for our room. View full site to comment or like
