Depending on your touring style and the ages of your group members, I don't think that's too many days in the parks. (But, I'm biased!) If you want a more relaxed pace and will be taking breaks for the pool (not out of the question in November) or for TS meals or if you want to see shows/parades/live music/etc. or spend time shopping, then your number of days sounds fine. With MP so easy to purchase as soon as you get through the gates, I would decide day of whether you want it or need it that day. Some rides have Single Rider lines -- if your group members are old enough and willing to use them, SR lines can be a great way to get repeat rides without using a FP. We like to schedule lots of breaks and down time throughout our park days, especially during peak crowd times. It just helps to alleviate stress. So having the luxury of plenty of days for nice meals, shows, repeat rides/shows/parades/do-overs if fireworks get cancelled/etc. is really helpful and keeps our sanity levels up. If your visit falls during Holiday Time, you'll enjoy having the extra time to soak in all the lovely details and decorations throughout the parks, DTD, the on site hotels, etc.
