People.....here is the voice of 'moderation'. Please, if you insist on taking liquids in your checked bags, be sure there is absolutely no way they can open and ruin anyone else's things. I'm all for freedoms and getting to do what I want, when I want. But, I have to tell you....if I got my checked bag at baggage claim and saw that my bag was now soaked, by someone else's 'liquid', well, I'm going to give cranky all new meaning.
There are plenty of ways of getting stuff that you may need but don't want to carry with you. Either buy it at home and then ship it down to your resort, rent a car and buy it on the way to WDW, get a towncar service and make a grocery stop, use a grocery delivery service and have what you want delivered to you.
There is no reason to pack soda in your checked bags. There is just too much leeway for an accident to happen. Carbonated beverages can be a bit 'unstable' in a plane. How would you feel if that Pepsi that you just had to have, spewed forth in the belly of the plane, and ruined a bunce of other passengers things? As well as your own!!! It's just not worth it to save a few dollars. Like I've said before...we spend thousands on a trip to WDW then obsess over saving $100 on groceries. Sometimes I think we all get a bit unhinged when planning...myself included!!
