You can buy a single day ticket. Do try to buy your ticket as soon as you know you are going. I would hate for them to sell out on you!!! We bought our tkts this am, only 1.5 hrs before we arrived. Glad we did it. Yikes! - some of the meeting rooms were small and the waiting q's were starting to fill up with people 2 hrs before the session! If there is something you want to see or do, get there early and save your spot. Many angry people standing outside some closed doors. Felt a bit in a frenzy because there was so much happening at once. Pin previews! Special stamp cancelling in the post office area! So many people in line to get merchandise signed! Disney Channel Autograph sessions! And all available without attending any afternoon presentations! It's a bit frantic but a good time was had by all! To see the opening, the Legends, and Art Linkletter too - all before noon!!!
