I flew down to Disneyland yesterday for my birthday, and had a wonderful time

(and thank you for asking)! But that's not why I called you in here today...
I made the choice not to carry my Sony Reader (I was afraid it might get broken on one of the coaster-type rides), and took a paperback book instead. Bad idea: between the flight, the airport, and waiting in ride lines I had enough time to finish my book, and start to re-read it.

I did spend a lot of time people-watching, but some lines were 40 to 80 minutes in length.
So my question to you: have you ever taken your reader to Disneyland (or any other reader to an amusement park)? Did it turn out to be a good or bad idea? Looking forward to hearing from you!
