I started out by collecting State Pins at the national Future Business Leaders of America conference in Anahiem. We traded for different pins each state brought.
In 3 hours at Disneyland, I bought 10.
I get them at every place whether it be a race track, Hard Rock Cafe, Planet Hollywood, etc...
I have over 250 Disney pins and over 500 total.
Most regular pins, not great big ones or limited editions run for 6.50. It was good to get a 20% cast discount, but I wish I was eligible for the 35%. No telling how many I would have now.

I would probally have her get a coffee mug if you are a coffee drinker.
It is more useful and durable than something like a pin or mickey hands that aren't much and may become boring to have after awhile. I wouldn't have her get something like the lollipops someone suggested.
