If you want to see as many lights as possible, this twinkling drive-through wonderland in the Dallas suburb of Grand Prairie never disappoints. Every year, folks pile in by the carload ($35 per car during the week and $45 on weekends) to cruise through four million lights and hundreds of custom displays set along 2 miles of path. The park also features a holiday village where you can hang with Santa; refuel with hot chocolate and snacks; enjoy an indoor laser show and trek through a lighted walk-through forest. And as if that weren't enough, the place boasts the world's largest animated light tunnel at the end of the drive. The park is open nightly (6-9 p.m. Sunday-Thursday; 6-10 p.m. Friday and Saturday) from Thanksgiving night until December 31.
