I can't believe you aren't deluged with offers in the mail.
Assuming that you won't let yourself get into credit card trouble, get a card with no annual fee. It is ridiculous to pay a fee when so many of them don't have one.
Get one that has rewards you can/will use. Airline miles are fun, but will your schedule allow you to travel? I am partial to the cold hard cash that Discover gives me.
Disney rewards are great if you will be able to use them. If you live a plane ride away from a park, your trips may be somewhat limited. IMHO, the "perks" of the Disney Visa are nearly worthless. (Criminey!! I live in Kansas--my chances of using a discount to see Lion King on Broadway are less than zero).
That said, I have a Disney Visa which I use for the very few times I can't use Discover. When I have I trip planned I use the Disney card exclusively to rack up points.
