I was at an sf convention a couple of weeks ago at one of the more…architecturally interesting hotels. The official name is the Westchester Hilton but we call it the Escher Hilton. The room floors on the south side are numbered 1 to 4. The room floors on the north side used to be numbered 5 to 8, now 2 to 5. The Transdimensional Portal is a very long corridor with several jogs in it, no stairs but does have a very small incline in the middle. It runs behind the ballroom/meeting space, goes from the 4th floor on the south side to what is now the 4th floor on the north side. Due to the way the floors were numbered, itt used to go from the 4th floor to the 7th floor. Hence why we call it the Transdimensional Portal.
There is a lovely square staircase, mirrored on one wall, with a gorgeous intricate chandelier. It starts in a corner of one of the jogs in the Transdimensional Portal, near no meeting space at all, and comes out in a narrow hallway downstairs, behind the ballrooms.
There is some function space/ballrooms on the north side, accessible by its own lobby and a grand staircase. If you are at all mobility impaired, the only way to get up there is to use the elevator in the south wing and hobble/wheel yourself over by way of the Transdimensional Portal. Or go around the tennis courts and in thru the north side door to get to the elevator in that wing.
To get from the upstairs ballroom space to the downstairs ballroom space, you go down the outer wings of the grand staircase, then reverse direction to go down the center staircase, turn left to go thru an unobtrusive hallway under the left wing of the grand staircase and into the lobby of the other ballroom. Reversing that path, you go thru an unobtrusive door at the far end of the ballroom lobby, into a narrow hallway that looks to deadend. Only after you go thru it do you realize there are stairs to the right. The grand staircase is five people wide. The hallway under the stairs is only two people wide.
And depending on where your room is and what the weather is like, the shortest route to many of the rooms is outside thru the gardens.
It’s strange but we like it.
