Billed as a high end 4 star, but the Bellagio this place is not. Service was terrible, particularly on the casino floor and the pool, where they shut half the pool deck on a beautiful day, cramming everyone into one smaller space. Clearly it is run for the convenience of the staff, not the guests.
The room layout is great, but furniture is desperately tired and in need of a full refurb. Tower layout means some loooong walks from the lifts.
Either stay at the Wynn or Bellagio if your budget allows, or just save your $$$ and go to the Park. Aria is not worth the premium it charges.
