We've done this 3 times and while the character lineup is subject to variation, based on personal experience, it's a good bet you'll see aforementioned Minnie, Hook, Tigger, Pooh, Penguins, and the Fairy Godmother, Also, I recommend requesting an indoor table if possible.
We had this happen recently - felt dumb because we usually triplecheck blockout dates, but we wound up enjoying ourselves by exploring the DL and GC Hotel grounds, then caught the Fireworks from the balcony of Catal.
A personal favorite is the beautifully hand crafted music box
A fun video from 2013, the story behind the music box with Clopin, Figaro and the even watch the Tangled Tower being put into the Fantasy Faire:
Of course, no trip to the Fantasy Faire would be complete without a visit to the Royal Hall. Loved this artist rendition, that's just how my girls are when they enter the Hall. ::sigh::
Took this next part directly from Disney Parks Blog:
“After walking into our main entrance, you will first go through a garden-like setting before entering the reception hall,” said Michel Den Dulk, Creative Director of Fantasy Faire for Walt Disney Imagineering. “Once inside the Royal Hall, guests will discover a beautiful gothic interior with nice wallpaper, wall cresting, wood finishes and chandeliers.”
Passing through a series of spaces, including the Grand Hall, you’ll have the opportunity to meet as many as three Disney princesses, from classic stories such as “Cinderella” and “Sleeping Beauty.”
Dont forget to grab a sweet treat from Maurice's Treats! At the time, (isn't there more now?) the adorable cart featured 3 “Twists” and a new signature beverage: Boysen Apple Freeze.
In a tribute to the historic Carnation Plaza Gardens, a shield over the archway leading from Fantasy Faire to Rancho del Zocalo in Frontierland displays the letters “CPG.”
