Wednesday there was a small fire in a service area in the Masquerade tower of the Rio, causing power outages, sprinklers went off on some floors, and some people were evacuated and given other rooms. The fire put out quickly, but the damage to some rooms on the 26-27 or so floors caused problems.
However today there was more smoke, probably from water damage to the electrical system, and more people evacuated, up to 1000 people affected and some people moved to other Caesars hotels.
Interestingly, we are scheduled to arrive at the Rio on the 31st, hoping for a room with a view of the strip, with friends in tow. My host called today and said we might end up in the Ipanema tower. Last year we were in one of those stupendous huge suites in the Masquerade tower. We shall see.
