From the Super Mario Wiki
The entrance to Larry's Chillton Hotel
“Mario:Gee, it's kinda dark!
Luigi:You bring a light?
Luigi:Well, maybe a Koopa will lend us his. If we, persuade him.”
—Mario and Luigi, Hotel Mario
Larry's Chillton Hotel, labeled Larry's Cave Hotel on its entrance, is a hotel found in Hotel Mario, owned by Larry Koopa. It is actually an ice cave which replaces doors with refrigerators and features other ice themes. Enemies found in here are basic enemies like Koopa Troopas, Monty Moles, Spinies, and Buzzy Beetles. Once this hotel is beaten, its interior explodes, Mario and Luigi barely manage to escape this explosion and Princess Toadstool has the even less fortunate fate of being carried away to Lemmy's High-ate Regency Hotel, where the Mario Bros. travel next.
- The Chillton Hotel is a pun on the word "chill" and the Hilton brand of hotels.
