A tv spinoff for Sony Animation's Hotel Transylvania films is coming to Netflix in 2025, which is to be about a Motel for Monsters, so much so that it goes by the name Motel Transylvania. The fact that it's to be on Netflix is exactly why Amazon Prime can't have any Hotel Transylvania films on it, the 4th film needs to be seen on the big screen and be mentioned in stuff to do with the box office as it was supposed to've done: https://www.change.org/p/sony-animation-re-release-the-last-of-the-hotel-transylvania-films-in-theatres-worldwide-on-a-later-date

Plus there won't be any streaming service to have an entire collection of Hotel Transylvania stuff unless Amazon Prime can get anything they have on it off it, everything Sony in fact should always have the same ownership and not be left out when it comes to just about anything unless to do with age ratings and certain themes. With that being said, I think that the day Motel Transylvania premieres should be held off until Hotel Transylvania 4 is no longer on Amazon Prime.
