It is not uncommon for hotels to renumber rooms when something famous or infamous occurs in them.
Years back my wife and I stayed at a famous beach resort that had an equally-famous haunted room. When we checked in, my wife, who was an avid reader of real-life ghost stories jokingly asked if we could have the "haunted room." To our surprise, the front-desk lady said "sure."
The hotel and ghost story had been featured in several books and documentaries, so we knew we had the correct room because of its position next to a flight of stairs where the ghost is reportedly seen wandering. The room's number, however, was very different from what is listed in all the books and TV shows.
If I remember correctly, the hotel where the movie "The Shining" was filmed changed their numbering system and eliminated the number "237" to avoid having its occupants harassed by other guests.
My guess is that Mandalay will shuffle the numbers on that entire floor and likely eliminate the number 32135 completely.
