And buying stuff while you're there....
I have the plastic card (paid the $6.95 onetime fee), so I used most of my webbie balance to buy Disney Dollars at my local DS (then used those to buy food, etc. at the parks). But I left my last $75 on the card and used that to buy stuff at the Virgin Store at Downtown Disney. (What I had left on the card when I got home, I used to buy clothes at Old Navy.)
