If you fly to WDW, you may want to consider purchasing some of these:
I posted on another thread, but thought I would start a new topic for those who didn't see it there. There are several similar products on the market but these seemed like the best deal with awesome reviews. I plan to bring a couple of bottles down with me in August, and a couple of bottles back home after Food and Wine. Can also be used for things like olive oil or vinegar. They are reusable - don't be duped into getting the single-use version.
Oh, that to be clear, this is a public service announcement - I don't own stock in this company or anything like that.
