On one of DHS’s two coasters, 24-passenger “limousine” trains launch from 0 to 57mph in under 3 seconds, sending them through a 92-second rampage through smooth corkscrews and turns that are intensified by fluorescent symbols of Los Angeles (at one point, you dive though an “O” of the Hollywood sign). The indoor setup is a boon, because it means the ride can operate during the rain. Cooler yet, speakers in each headrest (there are more than 900 in total) play Aerosmith music, which is perfectly timed to the dips and rolls. Strategy: There’s a single-rider line, though it’s not always quick.
