How about adding new rooms to the inn, such as the kitchen and garden? The kitchen would involve a quest to renovate this room and hire a cook who could be a halfling (after all, who cooks better in fantasy worlds than halflings). A halfling-cook would look like Alice, but of course she would be much plumper. The kitchen could also involve delivering supplies to it, and its mere presence could increase profits (guests would certainly gladly pay for the opportunity to eat a meal). Places where you could get supplies are the forest (or town park) (herbs and mushrooms), fishing village/seaside (fish and seafood), beth's farm (milk and meat, and maybe even Beth could recommend a young and innocent holstaur for work?) .
The garden could be a source of vegetables and fruits, and of course some beautiful alraune could live there and provide their sweet nectar to the kitchen. The garden would also involve a quest to clean it up and hire a gardener (a dryad, for example).
I read somewhere, probably on the F95 forum, that in the future new locations will appear on the map, such as mazes. How about a haunted castle ruled by a powerful and sexy vampiress (like Lady Dimitrescu for example)? She would live there alone, or in the company of several daughters, or other monster girls.
