Long lasting sweet treat recipe?

[LuluLovesDisney]

I want to bake/make something to put in each guest's "welcome box" for my wedding. I just bought adorable Mickey sprinkles and would love to use them. However, the items would need to last for about 5 days before some guests would receive them.

Is there anything that would work in this case?

I was thinking even rice krispie treats or chocolate dipped pretzels or oreos, figuring they might last long enough, but since chocolate melts so easily, it might not be the best to take to Florida!

Any ideas?

I was going to suggest the rice krispie treats, wrapped tightly in plastic wrap. They don't have to be dipped in chocolate, just put the sprinkle on when they are still setting up and they should stick.
