Basic casino hotel.  Expensive restaurants.  Great staff.  We were there for a conference, and, as with all casino hotels, had to travel through the casino to get anywhere.  But, the Doubletree staff were, to a person, incredibly welcoming and helpful, from assembling our mobility scooter when we unloaded it, to finding us a taxi or making sure we knew where we were going  when we left the hotel.  The concierge, David, got us discounted tickets for a couple of GREAT shows, even after Ticketmaster showed them sold out.
