You are a thoughtful big sister~

I hear you on eating the treats beforehand. I told my kids the treat bag with the snacks had to stay in the pantry until we left for the airport. I was thinking about other things to do and if you have a Walgreens they have quite a few Disney items (pencils, candy, stuffed animals, character cups) and they are reasonably priced. You could go online to the
Disney Store for a shirt and they often have sales. Sometimes
Walmart has Disney character shirts. So many ideas with this that can be done for not much money or more money if you choose to spend more.
