Well, whaddya know — Magic Kingdom runs a regular Monday tonight, October 19: no party, so the gates stay open till 10 PM with Early Entry at 8:30. Two things to plan around: the railroad is closed at both Main Street and Fantasyland stations while Villains Land goes up, and Carousel of Progress is still dark.
Even I couldn't goof this one up: ride the tallest standby before 9:30 — TRON was trendin' around 62 minutes at check-in — then save Seven Dwarfs Mine Train for that last hour before close, when the lines go soft. And if a Christmas party is on your list, opening night's already sold out; November 15 and 19 are the cheapest nights left at $194.
