We prefer that decorations are not hung on our walls. We do not allow anything to be taped to our walls. Balloons are a great addition. If you love balloons, we suggest two arrangements, 1.) for the front door, and 2.) for the cake table or gift bag table. Our space has high ceilings so balloons get lost in our space. I do not suggest balloons on the tables with the food and beverages as they often cause items to be knocked off the table.
