I'm not sure about anyone else's experiences, but we went on the Columbus Day holiday (Monday) when the rest of the park was pretty busy, we got to princess Fantasy Faire about an hour after it opened, and it was not crowded at all. We didn't line up to meet the princesses so not sure how long that was taking, maybe if you were doing that you'd need to be there right on opening, but for the show, story etc it was fine.
