Only tip is to arrive early! When Splash closed, the final day the line was hours long!
I will say some people tried to stick around to be the 'last to ride' Splash and either lost out or, were told to just keep moving - I can't remember which. In the end once the attraction closed to guests, CMs were allowed to be the true final people to ride. I can see them doing something similar for Muppetvision 3-D.
While I can see it might be fun to say, 'I was at the last....' it may be challenging. Just going the final day might be easier than trying to time it to be at the final showing.
