Last time I was at the parks I noticed that people were walking in and out near the parking booth at the harbor blvd auto entrance (they were walking in though a gate in the fence and getting on the trams to go to the parks) I hadn't noticed this before. Then at the end of the night it was announced that the Timon tram was for the katella walking entrance as well. ..
BUT... there was a bunch of conventions going on at the time. Is that entrance a viable way to get to the parks from Katella or is it just something they open up when conventions are around?
