We used MP for two days between Christmas and New Year's last year (the 28th and 29th - the 28th was the day after the Fantasyland power outage). It was our first experience with MP, and it was terrific. We didn't have park hoppers, and we did DCA the first day and DL the second to avoid EMH. For the two days, we experienced 38 attractions, using 17 FPs. Never waited longer than 20 minutes unless we CHOSE to (i.e. had some time to kill before our next FP and figured waiting 45 minutes for Soarin' was not a terrible use of time). However, by around 5:00, every attraction in DCA had run out of FPs. We still had several to use in the evening, but we were unable to book any more, and nobody cancelled any after that time. This happened in DL the following day, as well. By 8:30 at night, the only thing that still had available FPs was Splash because...December!
