Terri,
While resorts can fill up, I think that you should be OK, even booking in October. But it always helps to have a second and third resort in mind, just in case. My suggestions as great backups for Port Orleans French Quarter are;
- Port Orleans Riverside
- Coronado Springs
As for a 6-year old's birthday dinner, here are my top 3 choices;
- Chef Mickey's
- Mickey's Backyard BBQ
- Whispering Canyon Cafe
You might also consider (if the 6 year old is a girl) Cinderella's Royal Table. While there are no characters, as there would be at lunch or breakfast, that is actually a good thing. A magical atmosphere, and she is more of the center of attention!
Another choice is to hit a table service restaurant in the Epcot World Showcase that has his/her favorite food type.
Also, did you know you can order a special cake for the occasion? Visit
this page for more information on both the cakes, as well as other birthday related ideas!
Have a magical (and delicious) vacation!
