I went AT on the 4th july and air seemed a bit more gutsy than when i went in may but all other rides are the same for me!
For instance last year at scarefest we went on thirteen and i know theres a difference to the feel depending on whether u sit on the front seats or back but i went on it 8 times that day 0min wait and loved it like it was nothing
In may i only managed 2 goes on thirteen cus the drop got me feet tingling and it seemed more intense?
Subterra was a similar scenario,
So for me it all depends on how u feel on the day which can give a more or less experience!
