It's always a treat to visit Disneyland and California Adventure parks, and starting on October 8, things will get a little geekier. Disney's California Adventure will open its new "digital world" called ElecTRONica to celebrate the opening of TRON: Legacy this December.This new world will come packed with a futuristic dance club, an authentic recreation of Flynn's arcade, live entertainment (with lasers!), and a TRON: Legacy video game area where you can play the latest title. Good news is, Disney hasn't released an end date for ElecTRONica, but the bad news is it will only be "lighting up" during the latter part of the week regularly (Fridays, Saturdays, and Sundays), but will be open every day during major holiday weeks (Thanksgiving and Christmas). I'm going, are you?
