Well, yesterday at 3:00 PM, Shrek was a 15 minute wait. At the busiest time it did get to 45 minute wait on MIB but part of that reason is they had to do a couple of shutdowns from guests doing unsafe things . (I really wanted to say guest stupidity.) They then had to reboot and cycle the cars.
It really wasn't busy either Monday or Tuesday when I went this week. I'll be there tomorrow also.
