As you can see from my signature, we've gone to WDW in November every year since 2000 and we love that time of year. Generally, the weather is great and plenty warm enough for swiming. Of course, being Florida, there is always the chance of rain or cooler weather, but it usually only lasts for a day or two. In 2001, we caught the tail-end of hurricane Melissa, so it was cloudy and cool for a couple of days but cleared off by mid-week.
The crowds at the parks are very manageable. MGM gets crowded on Super Soap weekend (Nov 8-9), but most of the crowds are waiting in line to see soap opera stars, not ride the attractions. We usually just avoid MGM on those days and go later during the week.
Also, Epcot's attendance picks up due to the Food & Wine Festival that runs through November 16th, but it's usually only noticable on the weekends. This event is one of the main reasons we keep coming back this time of year--it's one of our favorites!
Due to these two events, the Epcot resorts are usually fairly full. We usually stay at the Beach Club or Yacht Club the second half of our trip, and even with a sold-out resort we have always been able to find a table at Stormalong Bay (the pool that the resorts share). The first half of our trip is usually at the Polynesian, and it has never seemed overly crowded to me.
Bottom line: I think you will be very pleased with November. Have a great trip and thanks for the job your husband (and you) do for our country.
