My poor wife grew up in NY and UT and never went to Disneyland as a kid. Me growing up in Cali I went there alot thus DL has a lot of special memories for me. About 10 years ago I take her and she was like "what's the big deal?" We are regular California season pass holders and our kids love DL.
Fast times is a classic but if you wait too long you'll outgrow it. My HS experience was very very much like the movie - except I didn't have sex starved girls after me.
"Are you in my class?"
"I am today!"
