!!Trivia:
* ''Hotel Mario'' is very similar in gameplay to ''[[http://www.atariprotos.com/5200/software/looneytunes/looneytunes.htm Looney Tunes Hotel]]'', a game planned for the Platform/Atari5200 but cancelled. It's unknown whether ''Hotel Mario's'' development team actually knew of this game.
* Similarly to ''Music/WithTheBeatles'', ''Hotel Mario'' holds the dubious and downright morbid distinction of having been released on the exact same day of the exact same year as Music/KurtCobain's suicide.
* Later, and by sheer coincidence, ''WesternAnimation/TheSuperMarioBrosMovie'' would be released on the 29th anniversary of ''Hotel Mario'''s release.

!!Trivia tropes:
* AccidentallyCorrectWriting: Toasters ''do'' reheat toast.
* ActingForTwo: Creator/MarcGraue voices everyone except Princess Toadstool.
* BuryYourArt: The game has never been reissued in any way since it first came out, thanks to its negative reputation among not only fans and critics, but also Creator/{{Nintendo}} themselves, who refuse to acknowledge its existence.
* ContractualObligationProject: This game, along with the ''[[VideoGame/TheLegendOfZeldaCDIGames Zelda]]'' CD-i games, exists as part of a contract Nintendo and Philips made after the cancellation of the Platform/{{SNESCDRom}}. Consequently, Nintendo had little interest or oversight other than ensuring that the characters were on-model in the packaging and manual artwork.
* DummiedOut: Although the game's only in-game "tutorial" is telling players to ReadTheFreakingManual, there is an unused recording of Mario (apparently a temp track done by someone other than Creator/MarcGraue) instructing the players on the game's basic mechanics. This is still present in the released build's files, even though the corresponding gameplay footage present in the [[https://www.youtube.com/watch?v=tk2i07t-uE4 beta build]] was cut.
* KeepCirculatingTheTapes: 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 [[CanonDiscontinuity 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.
* OrphanedReference: When instructing the player to "[[ReadTheFreakingManual check out the enclosed instruction book]]" in the intro cutscene, Mario holds up one finger. This is a holdover of the cutscene's [[https://www.youtube.com/watch?v=tk2i07t-uE4 original dialogue]], where he would have told players to press button 1 for instructions or button 2 to skip ahead to the game. The animation of him holding up two fingers was cut in the final version, which freezes on the frame of Mario holding up one finger.
* StarMakingRole: For Creator/MarcGraue.
* ThrowItIn: Marc ad-libbed Mario's ShoutOut line, "Hey, you, get offa my cloud!"
* WhatCouldHaveBeen:
** 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 ''VideoGame/SuperMarioWorld'', 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 ''VideoGame/SuperMarioOdyssey'', over two decades later.
** Hotel 6 has [[DummiedOut no game data]], with the internal level order skipping from 5 (Ludwig) to 7 (Wendy)[[note]]contrary to UrbanLegendOfZelda, no, it cannot be unlocked by beating the game in under an hour -- it just doesn't exist in there[[/note]]. This is further supported by Bowser's dialogue in [[https://www.youtube.com/watch?v=tk2i07t-uE4 the beta intro cutscene]] where Bowser mentions eight Koopa hotels instead of just seven. [[http://www.blackmoonproject.co.uk/interviews/trici_venola.php 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.
** [[https://www.youtube.com/watch?v=tk2i07t-uE4 In the beta opening, when Mario is reading the letter]], Bowser's voice would have played over the letter instead of Mario reading it out loud.
