I thought this was nice.  I stayed here shortly after grand opening, so everything was clean and new as expected.  It was difficult to find the correct elevator banks to get here - this hotel occupies the top 4 floors of Mandalay Bay.  I stayed in a standard room.  The amenities in this hotel are great!  You have full access to the Mandalay water resort, in addition to private Four Seasons guests pools that are much less frequented.  Great restaurants too.  Verandah and Lupo restaurants are favorites.
