We just got back from Bellagio where we were upgraded to a lake view newly renovated room on the 27th floor. The rooms are well done and the view was great!
We were surprised at the upgrade at check-in (no $20 trick) since we were on a comped room; we just asked nicely if a lake view room was possible. We were pleasantly surprised when the clerk called and got permission to give us a lake view on the 27th floor. We did give her a $20 tip--and she was very nice about it and said she would put it into her Christmas fund :)
They are still working on the other end of the hall and have a black curtain and a guard posted 24/7 to keep people from wandering in the construction area. No noise problems noticed. There were a few glitches in the room (safe didn't work, drain in bathroom running slow ect...) things that happen when new construction is going on. All problems were addressed quickly and efficiently.
Let me know if you have any questions--we love staying here and hope we are able to get comps again (I can't figure out M Life) We didn't have offers from the other properties so were surprised when we got the offer from Bellagio!
