Any unique snack ideas or good ideas for packing them?
I find among the best snacks if any to bring are something like a granola/power bar and oranges. Then you don't have to worry about keeping the food cold.
When I say a power bar, I mean the kind that's chock full of healthy stuff, not the pop tart kind. The healthy kind has protein, so that will actually help hold us over vs. ones that simply raise your blood sugar.
Oranges/citrus are a good healthy snack, and they have a big plus that thy are heat tolerant, don't leak, and don't get gross like bananas. apples and maybe pears can also be okay, except some pears get mushy. apples and pears can be individually wrapped in saran wrap, which helps. also, you can't peal a grapefruit like you would an orange if need be.
truly, I'm not a big an of lugging around much stuff all day in the parks.
I love strawberries, but often if you put them in the tiny dorm fridges in most hotel rooms they emit a strange odor, at least conventional ones. It has happened to us several times.
One option, especially in season is to stop at Orange world on 192, if you come in that way. They have excellent produce!
Another possibility is that many of the Publix have a decent prepared foods section. For the most part, we only do that if we plan to eat the food right away.
Generally, I am a big fan of yogurt. I have yet to find a great way to keep it at WDW.
If you are staying on property, you kind of can't count on getting a decent fridge. Some of them just don't get very cold. I hear they have replaced many of them, but they can still be iffy. that said, our most recent fridge had the opposite problem, it froze everything!
