As for gadgets to help with efficient packing, a small handheld scale could be useful to ensure each pack stays under the recommended weight. It can be frustrating to have lopsided goodie bags, and a compact scale could ensure things are fair and evenly distributed
Also, instead of relying on flimsy plastic bags that can tear, sturdy drawstring bags could make packing and transportation easier, especially if they're provided in colorful designs that match the theme! Maybe even eco-friendly options - reusable cotton or jute bags would be a cute keepsake for guests and reduce waste.
