Take the card you get from costco to the ticket booths,
not the turnstile.
Then you go to the turnstiles and
finish up at AP guest services at the "Bank" on Main Street. (On the right - opposite City Hall)
This is where they take your picture and give you the plastic card that you keep.
We wanted to get an early start the next morning,
so we got our cards on Friday night and added parking to mine.
Just in case I want to take off without hubby on a whim.
It was pretty busy,
First night for the holiday parade/fireworks/etc.
It took us about an hour for the
ticket booth, turnstile line, and AP line.
Parking was $59 to add for the year.
I even remembered to ask for the AP discount when I got food.
10% off.
Every little bit helps.
