I just wanted to chime in. We spent today in the park, and have tickets for tomorrow as well. I think two days will be more than enough in the park. We are planning only a half day tomorrow, and will have done everything. The lines were very short for everything today (Monday June 26), and fast passes were available all day long.
Do not miss Mystic Manor. It was fabulous. The Mickey Storybook show was also excellent, but be sure to sit on the right side of the theater because some parts have English subtitles that are only shown on the right side of the theater. We sat on the far left, and I couldn't read them.
We are staying at the Hollywood hotel and love it. We walked over to the Explorers Lodge and it's like a tiny Animal Kingdom Lodge, our hotel's pool is significantly better because it has a great water slide.
