One of my favorite tips I found online before the trip was to buy and bring your own light-up trinkets. There are those carts everywhere after dark with all sorts of very pricey glow items. I found that having my own that I either got from my store (I know that's cheating) or from the Target $1 section, not only kept the kids from asking for stuff from the carts, but it really gave them a boost to get us back to the hotel each night.
