speaking as someone who went to disneyland every year between roughly 1976-1984, i think that my personal favorite years were sometime between 1976-1980. Before the indiana jones ride, just before the log ride. while tom sawyers island was still cool, all the rides worked, and the mission to mars was still futuristic. Also after I was old enough to go on all the rollercoasters. Also before the lines had hour wait times. When I first started going, you could run through most of the lines and only the river boat ride was long enough to be boring, but usually there were enough cool waiting line distractions to not make it too bad.
