Inns

Inns (synonyms: roadhouses, public houses; example toponyms: The Prancing Dragon, The Inn and Tea) are locations where travelers may sleep for the night. In fantasy worlds they are often important locations along a journey and may also contain or be a part of a tavern. In game-oriented worlds inns are often buildings where heroes can sleep, recover health, or save their progress. Inns are found in towns, cities, and along roads, trade routes, and at crossroads. They are home to innkeepers, servants, and travelers.
When designing inns for your fictional world, consider the types of people that often use them. Are the rooms sparse, or relatively luxurious?
Older inns may have extensive crawlspaces and peepholes. They may also contain hidden rooms.

Why would the rooms of your inn be at full capacity and who is using them?
