This game is irredeemably bad. Labeled as a "tower defense" game, it is one of the weakest examples of the genre. Bad Hotel is to tower defense what peanut butter and jelly sandwiches are to haute cuisine. The game is obviously meant for a phone-based clicker game, which is fine, except the gameplay is severely simplistic and incredibly drastically boring.
The game works like this: there is a time limit for each round. You start off with a small hotel and some money. You can add parts to your hotel with the money you have an earn throughout the round. Enemies, such as bomb-carrying ducks and burglars, will try to damage and steal money from your hotel. You can add turrets, expansions that have mines in them, etc. At the top, the ticker displays when there are periods of calm and when there are periods of incoming attack.
I got this in a bundle with a bunch of other games that had Steam cards. Otherwise, I would never have added this title to my Steam Library. IMO, the only good thing about this game is that has Steam trading cards. It's not the worst game out there, by any means, but it's not particularly good, either. I can see this being enjoyable on a smartphone while waiting at the DMV, but this is a pretty tame affair for a PC title.
