I have had an AP only for the last few years. When a single day ticket got to be so expensive that it didn't make sense to buy it just for a single day is when I got my pass. Iam 39 years old. The last three years I have been there about 150 times. Before that I averaged about8 times per year and less so as the tickets got increasingly expensive.
I would say I have been there approximately 500 times.
