Brother I tell you, but money is one of the first things that stop working in disrepair apocalipse, maybe you can buy cheap things around, however it is unprofitable that you can rent a hotel or buy expensive things, because who has not been going to sell, because of financial instability, at least not in the first few days before knowing how things are going to get, worst practically nobody would go to work, the more a hotel opened, the government would strive to only keep the basic resources safe, water , electricity and active communication, you yourself said that in the next wave the world could end what leads us to think that the situation now is horrible with monsters in almost every corner, like keeping a hotel in a place like that.
