I don't live there anymore, but when I did, it was about a 90 minute drive or so, depending on traffic. We'd go 2-3 times a year, whenever we could get the best SoCal resident deal. We'd leave super early in the morning to make it there close to opening, and stay till closing. This was back in the early days of DCA, back when they were pushing park hoppers like mad to residents. We'd spend the morning at DL, hit the biggies, head over to DCA to do a couple things there (there wasn't much there yet) and then back to DL for the rest of the day and Fantasmic. I remember once they did a really awesome two day hopper price, so we did two days straight of opening to closing with a 90 minute drive each way. Whew!
