Koopa hotel

The Koopa hotels, or simply hotels, are seven different hotels scattered around the Mushroom Kingdom during Bowser's take-over in Hotel Mario. Mario and Luigi go through each of the hotels to save Princess Peach and the kingdom. Each hotel is owned by a different Koopaling except for the last one, which is Bowser's. Strangely, Iggy Koopa did not own his own hotel and shared it with Bowser, appearing as a mini-boss in it.

These are all the hotels in the game:
 * Morton's Wood Door Hysteria Hotel
 * Roy's HardBrick Hotel
 * Larry's Chillton Hotel
 * Lemmy's High-ate Regency Hotel
 * Ludwig's Thump Castle Hotel
 * Wendy's Blitz Snarlton Hotel
 * Bowser's Seizures Palace Hotel

Trivia

 * Inspecting the level data shows that there is a missing sixth spot, as the game loads the seventh spot right after the fifth. This would have presumably belonged to Iggy, as he is the only Koopaling to not control a hotel.
 * A "Cheese Hotel" level was proposed during the conceptualization period, but was rejected.
