Hi Beth!
November is a great time to visit Disney world! The weather is still pretty warm at that time (but not extreme heat), and the crowds are generally smaller...
Sounds like you'll be taking your daughters to the princess dining at Akershus Royal Banquet Hall in Norway at Epcot. Even if you make reservations at Akershus before the park opens, you'll be allowed to go to the restaurant. Park admission is required, but they usually have the other sections tapered off, as well as staff directing you to the restaurant when you enter the park.
Now if you're looking for Early Extra Magic Hours to the Park, you can find it by clicking here, then choosing the month of November.
Taking an early or later breakfast would depend on your plans for the day. If you plan to spend the day in Epcot afterwards, I would try an earlier breakfast (no later than 9:00). If not, then you can take a later breakfast around 10 or 10:30 if necessary. Since Epcot gets pretty busy near lunchtime, and it's generally an 1 hour to 1 hour 15 minutes at the restaurant, you may try for the earlier reservation to catch a few rides afterwards before it picks up.
Have a magical time on your trip!
