Managed to do Saw alive, MBV and Blair as walk on last night. Queued an hour for studio 13 at 6.00 and 40 mins for cabin around 7.45. Great night and very atmospheric around park.
Best mazes for me were MBV and studio 13. Worst was cabin due to bumping into too many other groups ruining atmosphere. Guess each experience is different and ran out of time to try cabin again.
