Unless you're a WaltBoy, this fun little video might not make a heck of a lot of sense. Just know that ADR = Advance Dining Reservation, and that ADR's are a branch of mathematics peculiar to getting seats at your favourite DisneyWorld restaurant. The upshot, you currently can make an ADR 90 days in advance (soon to be 120 days), and the competition for these things can have all the drama and frustration of getting tickets to a Beatles reunion concert. In reality, it ain't that bad - but ADRs have become a meme all their own in the DisneySphere. Enjoy!
