Well, I went ahead decided to fly down instead of drive. I figured it'd be easier to do, especially since I'm staying on-property and will likely remain generally confined to property (thought I might sneak out to Domu...gotta have my wings and ramen) and Magical Express will still be a thing during this time.
Also, by the time you add up parking fees and gas, it's not much cheaper than the cost of the ticket anyway (based on traveling from Atlanta to Orlando), so I might as well travel "passively" for the roughly the same money.
