- Accidentally Correct Writing: Toasters do reheat toast.
- Fan Nickname:
- Keep Circulating the Tapes: The game is not available in any other platform, and given the CD-i's notoriety for being next-to-impossible to emulate properly, those who wish to play it will have to pay a lot of money just to get a copy (and even more for those who don't have a CD-i). Nintendo has made it clear this game never happened, so even if they somehow owned the rights, they would have no appetite to put it out on their Virtual Console platform or anywhere else.
- Old Shame:
- Along with the Zelda games, Nintendo prefers not to bring up this debacle of a game nowadays.
- Averted with Marc Graue (who provided the voice of nearly everyone in the game). In an interview, he said he had lots of fun doing the voices and he's happy that they're being used in YouTube Poop despite being more than two decades old.
- Star-Making Role: For Marc Graue.
- Talking to Himself: Marc Graue voices everyone except Princess Toadstool.
- Throw It In!: Marc ad-libbed Mario's Shout-Out line, "Hey, you, get offa my cloud!"
- What Could Have Been:
- This wasn't the only Mario game planned for the CD-i. Two more, Super Mario's Wacky Worlds (a CD-i exclusive successor to Super Mario World, and probably the most promising of all the CD-i Nintendo games, released or otherwise) and Mario Takes America (an educational game) were planned, but were cancelled due to a variety of issues. That said, the basic idea of Wacky Worlds, Mario traveling the world, was (unintentionally) revisited in Super Mario Odyssey, over two decades later.
- Hotel 6 has no game data, with the internal level order skipping from 5 (Ludwig) to 7 (Wendy)note . Accordingly, a "Cheese Hotel" was among one of the concept drawings, but development was disgusted by the idea and promptly had the artist sacked. Presumably, this would have belonged to Iggy, who doesn't have his own hotel in the final game.
- Hotel Mario is very similar in gameplay to Looney Tunes Hotel, a game planned for the Atari 5200 but cancelled. It's unknown whether Hotel Mario's development team actually knew of this game.
- Similarly to With the Beatles, Hotel Mario holds the dubious and downright morbid distinction of having been released on the exact same day of the exact same year as Kurt Cobain's suicide.
