Drinking around the world is so fun! Some tips- make sure to have a hearty breakfast. One time, we had a really early ADR at Chef Mickeys that morning, got to Epcot around rope drop, hit up Future World and made it to World Showcase just before noon. Definietly pace yourself, and incorporate snacks too! IMO, the premixed sugary drinks are a waste of money. They'll use one regular bottle of tequila in the entire blended margarita mix- that works out to less than 1.5oz of liquor in your $10 slushie. But, if it's really hot, I'll get the GM slushie from France and find a bench in the shade to cool off and people watch. It is going to be an expensive day, so budget at least $100 for that day.
