Has anyone done this? We're planning on booking one night with park tickets with aa miles and then booking another night separately. I realize it's probably not the best bang for your buck but we got 40000 miles just for signing up for the card and we don't need the flight. I was just curious as to how it works. I think we're supposed to give a confirmation number at the park ticket booth to get our tickets. Just wondering how smoothly this goes and if it's possible to upgrade our tickets at the park. Thanks in advance fir your help!
