Greetings Carshundra!
Thanks for stopping by the Disney Parks Moms Panel. Oh, Tiana! That super smart southern belle who can whip up a mean jambalaya - what is not to love? Currently, she does not have a character dining location that she frequents, and while I haven't verified this with The Mouse, I think that she is too busy helping the Chefs in the kitchen to come and greet guests in the dining room! Make sure to keep an eye out on Disney Parks Blog, they will be the first to know all of her plans!
Never fear though, there are plenty of places to see your favorite Princess! She and Rapunzel greet guests every day at Princess Fairytale Hall. Then she joins her Disney Pals and other Royal Ladies at Disney Festival of Fantasy Parade. If I were you, I would take a page from Tiana's book and combine the Parade with a fantastic meal! Tony's Town Square Restaurant is the perfect compliment to the festivities with it's dining package.
Now if you want to sleep like a Princess, the Royal Guest Rooms at Disney's Port Orleans Resort - Riverside are the perfect royal decree! Regal furnishings, portraits of the Princesses, and a magic fireworks headboard all combine to create a Fantasy suite!
Carshundra, I know that "good things are sure to come your way" on your upcoming visit!
