The Capri Tower at Imperial Palace has closed and has reportedly been demolished to make way for Project Linq.
The Capri Tower was basically a motel behind Imperial Palace. The room doors led out to outdoor walkways, although the interiors were the same quality as Deluxe rooms.
I never was unlucky enough to stay in one of these rooms, but from what I can tell it appears as if they suffered from lots of noise from the nearby parking garage.
This should be the first of many changes at IP to make way for The Linq. The hotel will likely be re-named and re-themed as part of the project. I suspect there will be room and public area improvements also.
