Based on my past experiences in the Downtown Disney/Pleasure Island district, I would say that tripod use would have to be a complete guerrilla effort since the security and law enforcement people seem to think it's against the rules
If I'm ever using a tripod at DTD, and security approaches and tells me, "We don't allow professional photography here!" I'll just give 'em the standard Jack Sparrow reply:
"I'm terribly sorry, I didn't know. If I see one, I shall tell you immediately!"
I'll enjoy seeing new stuff come to DTD, but I will never forgive Disney for closing the Adventurer's Club.
