We received this offer in Feb and since I knew we wanted to fly to WDW I signed us up to earn enough points to fly free.
Since then I've purchased all four round trip with points and decided to continue using the card because we are only 28,000 away from earning the SW companion pass for 2013!!!
This to me is the most awesome benefit! So we decided to continue having all of our monthly bills charged on this card and we pay it out in full monthly.
I also use the SW shopping portal if I'm going to do any online shopping. All of my
Disney store purchase have given double points

(excluding gift cards). With special promotions, I've earned 16 per $ for ordering from stores like Brookstone and Childrens place thru the shopping portal.
Compared to other credit cards we have found this one to be the most reward worthy

since airfare is usually the caveat when we want to travel
