Mack ... I support personal freedom as much as the next guy. But I can't see any reason for you to carry a large folding knife into Disneyland. Disneyland is a pretty safe place - it's not like you're going to get trapped in a roller coaster for several days. You can take an exit and escape (!). Try to remember ... Disneyland is a family establishment. Think "Moms and kids" and adjust your gear to be compatible with that objective.

It is possible that when they search you - on entering the park - that they might object to a knife with a large blade. I don't know exactly what that policy is - but why test it?? If there is a problem, I'm guessing that they would either ask you to store the knife in your car in the parking lot, or alternatively place it in some sort of secure storage and pick it up when you left Disneyland. Either option is good ... I can't imagine a need for a large folder in that environment. In the event of a major emergency inside Disneyland, the place is FILLED with items that you could use to improvise survival techniques for just about contingency. Seriously.

Some amusement parks actually sell knives. Knottsberry Farm definitely has a vendor inside their park that sells knives and long-bladed weapons. The assumption, of course, is that you would pack up the item and take it home. Not all the parks are paranoid about this gear.
