I voted Yes based on the assumption that people who needed to would be able to pick theirs up and leave early.
If that is not an option, then I'd have to cipher on it more to decide which way to vote.
My expectation is that, if you allow people to pick up early and leave, the end of day presentation won't take as long as you predicted.
Also, as an accomodation to keeping the whole process shorter, I would vote for having the presentation be for just the top 3, and having 4th and 5th still pick theirs up the way it's done now.
