Oh my gosh, how annoying of the hotel. How can they be screwing up the rooms like that?!
Would it be any easier if guests booked through you and then you bulk booked the with the hotel?
As for the jars, I like them as they are. Like you say, you don't want to detract from the sweets inside. Plus you want people to know they can eat them and aren't just on display. If I was to put ribbon on them the only place I'd put it is around the top where you can see the rubber seal through x
