I was just looking into this today and have a question as well.
We are heading down to WDW in October, and if I apply and am approved for the SW card, I could use it to pay off our balance with Disney for the room and get some groceries and hit that $2k mark right away. I'm not worried about carrying a balance, as I already have the funds to payoff the room, I just haven't yet, and the 50k points means our flights would be completely free, but I guess it just seems too easy? Is there anything I'm missing here?
