We honeymooned in Disney after our DFTW, 2 day at the Grand, a 4 night cruise on the Dream, and 7 nights at AKL. I booked all three with my maiden name, especially the cruise. My hubby was the lead on all three reservations. Even on the cruise they asked me if I wanted to have my married name on my KTTW card.
When I asked about what to do if I lost my card, the CM said that having stayed at WDW 27 times previously, they could surely match my ID to my account and since my reservations noted my honeymoon it wouldn't be a problem.
