I went around that time last year, well I went all the time last year, and no matter if it was raining, suffocatingly humid, or a perfect day, the park is never going to be low on guests. The only time it was ever empty was the one time i dropped something off of Magnum and was stuck in the park until 2 in the morning trying to find my stuff with park security.
Life has it's ups and downs, might as well make it on a coaster!
