(Maybe Wodehouse could mention the other tabs? I don't remember seeing any reference to them, nor did I see anything in the bookcase information.)
Missing the tabs was a problem one of my early playtesters had too, so I added an explanation about the different tabs If you don't have any amenities chosen when you first check in guests. But I'll try to make this clearer, and mention in the bookcase too - thanks for the suggestion!
By the way, you mentioned the Amenities menu in your first post... I was just curious as to which menu you were referring to, if it wasn't the "Amenities" tab in the "Rooms" menu? (This will help me better understand the player's perspective.)
