Mysterious dumb waiters to rooms and floors with no other entrances

Im about to take a shower- here are some quick ideas.

The interior of the hotel is much larger than it first appears. In fact, the longer you stay, the bigger it seems to get.

The deeper you venture into the hotel, the stranger—and possibly more dangerous and unsettling—it becomes.

Some people have ventured too deep into the hotel’s halls and rooms, never to return.

Certain rooms are occupied by seemingly normal, even helpful, individuals.

Mimic mini bars (some mini bars are just fully stocked mini bars though)

Never use the elevator in case of fire.

you can check out any time you like but you can never leave

Joe won’t be losing the plot here. Actually no, Joe from Downfall would make for an amazing cameo encounter in this setting

Bonus points for sudden Cat Lady intervention, because Susan is the one good Brit
