This giant, drivable holiday amusement was built for fans of twinkly lights and loud, festive Christmas music. Folks come from far and wide to visit two drive-thru play parks, where giant snowmen flash, colossal Santas flicker, and cutie-pie elves glow in time to music piped directly into car radios. Billed as a "family holiday driving experience with synchronized Christmas lights," Illumination claims to be the world's largest animated holiday show — and it's certainly more than just a bunch of lights plugged into an extension cord. Shiny Yuletide features include a 100-foot-wide nativity scene and something called Santa's Portal, a 500-foot-long sonic tunnel filled with just some of the attraction's 1.7 million pixelized lights. Illumination will be held this year at Tempe Diablo Stadium and Westgate in Glendale. Just look for a gigantic glow in the December night sky, and start driving toward it.
