IMO, this is a bad move for ASIS. Sure, the junior employees who get left behind on the last days of a show, and the tear-down crew, will support this.
From a marketing budget perspective, it is already getting hard to justify ASIS for many manufacturers, and this move just reduces the amount of time you have to meet with attendees. Once you are there, the costs to staff additional days/hours are pretty small in the grand scheme of things, now ASIS is basically devaluing manufacturer's marketing investment in exhibiting.
I support the move to start on Tuesday instead of Monday, that always seemed like a decision that reduced Day 1 traffic and worked against the goal of the show.
The keynote opening onto the show floor is an interesting move, but it has a very "exit through the gift shop" tone to me. If you have to force attendees onto the show floor, then you need to reevaluate things from the top.
