Minecraft wiki entry for Shelters, associated text: Build a large and well-defended structure with private rooms each containing a bed and chest (possibly a furnace and crafting table too). For additional style points, decorate the rooms nicely. Use a locking mod, and charge people to stay at the inn; when they rent a room, add them to the list of people who can unlock the door and chest. You may want to hire people to man the front desk, keep records and collect bills. This is especially useful if you build it near a dungeon, as players will want to have a well-protected "base camp" when setting off to explore.
