You definitely want to do Boofet for sure. $45 and it's an all you can eat Buffet that starts at 5. You get let into the Mazes 30 minutes before the GP gets let in. I got about 5 mazes done in that time frame last night (Wax Works, The Depths, Dark Entities, Paranormal Inc, and Origins).
After doing those 5 you can go do Dark Ride, then Mesmer, then Pumpkin Eater and then you're done with the Mazes.
