caroline inn is kinda empty in and there is not much reason to use it so what i suggest it maybe it has “pleasure for hire”(if u know what i mean) and i will give u buff/debuff so it will be like 50/50 chance and you cant use it until the next 24hours and these buff/debuff wont go away by sleeping, dying, debuff remover(if there is an item like that in future).
also the inna could have multiple table where u can play different type of mini game with and without ur friends and those mini game will also have small quests and story.
