The Humble Hotel in My Singing Monsters was released with the 1-year anniversary update on September 3rd 2013. This Humble Hotel is a structure that can be found in the structure section of the game.
What it does?
The Humble Hotel allows you to place your monsters into the structure giving you more space without the purchase of more beds from the castle. It starts off with 10 beds free then once those are used up you can upgrade the Humble Hotel to get even more space for your monsters if you wish.
You can only buy one of these structures per island for your game and you cannot have multiple copies on a single island.
