I noticed that in the New Rose Hotel, you can look out the window to see whats goin down on the streets. There should be a fire escape that connects to room windows, so people could sneek in if you leave it open or unlocked or something.
The building was retrofitted by gutting the space that used to be occupied by rooms and using helos to drop plastic prefab cubes into the same space. The structure of the building stops where the hallways do.
There is no fire escape to individual cubes.
This is why it's the -New- Rose Hotel and not just the Rose Hotel. :)
