I hope I'm posting this on the proper board...... If I buy diet coke at the airport (hopefully they sell cans in a 12 pack or in some package of 20 oz bottles), can I just put it in my carry on bag? I know there are liquid resrtictions on planes but if I buy my diet coke at the airport, after I've gone through security, I should be good, right? Not sure the airport even sells diet coke like the grocery stores do. What to do? Diet coke is expensive in the Disney!! Any thought on this anyone?
