Well after doing all the math, the annual pass made no sense at all. I called up universal and asked what tickets would cost being an annual pass holder. According to her you do get 15% off tickets, that is standard gate tickets 1 day 1 park. So the halloween horror pass frequent scare tickets, the 2 day base tickets etc, no discount. In fact it was substantially cheaper to go to undercover tourist site and just by one of there packs of tickets and pay for parking 3 times @ $45 bucks. Total buying my tickets was 400 bucks and then parking will be 445 total. Had I gotten the universal premier pass and picked up tickets for everything total would be $559! Its unreal how they gouge consumers. The rep over the phone said they made changes not that along ago so the annual pass holders wouldn't get a discount off all tickets, which is how the market it in there site.
Thanks again to everyone who gave valuable input.
