Aloha, and Welcome to the Disney Parks Moms Panel, Jase!
'Ohana is one of my favorite Walt Disney World® Resort restaurants. You will most definitely feel like family the moment you are welcomed by your Cousin/server for this family-style character breakfast. I also love seeing Aloha Mickey in his Hawaiian finest.
There are two merchandise locations for you to choose from at Disney's Polynesian Village Resort.
The BouTiki Gift Shop is located on the left-side of the Great Ceremonial House (lobby) when you enter and should have autograph books. If not, head upstairs to
Moana Mercantile, I know for a fact this location has autograph books. The best part, it's just steps away from the check-in desk for 'Ohana's. Making it very convenient for you to grab your princess an autograph book while you are waiting for your table.
I hope this helps, Jase. Please let us know if you have any additional questions. We are here to help you plan a magical vacation.
Mahalo!
