You are leaving Saturday October 10th or Sunday October 11th?
If you are leaving on Sunday...you could either hit the Cars and Coffee cruise in Irvine (right down the 5 fwy from Anaheim) or the Donut Derelicts Cruise in Huntington Beach (and then cruise the beach). Huntington Beach is about 15 miles from downtown Anaheim...
If you want to go to either cruise...you better plan on getting up early...as they are both done by 9am!!
