I saw this in match 78836798. Around 22:45 (in replay timer)--Doorman carts Mirage through the door, Mirage ends up outside of the map geometry instead. Eventually falls through the map and gets stuck in the tunnels.
Nothing in the description of Hotel Guest or Traveler suggest you can't simply teleport out of the hotel, and Traveler is not actually disabled while in the hotel, so I'm assuming this is a bug.
Match ID 34732278, at 27:20--it looks like the Death Slam tried to target the top of the patron's head instead the ground, causing enemy heroes to be scattered instead of land in a tidy little group.
