@ten6mom - I'm going to address walkability to hotels for having a cocktail for you.
If you are in Magic Kingdom, the Contemporary Resort is walkable from there. It's about a 10 minute walk. If the monorail and boats are running, you can reach Grand Floridian, Polynesian and Wilderness Lodge (boat only) this way.
If you are in Epcot or Disney's Hollywood Studios, you can walk or boat to Boardwalk Inn and Boardwalk Villas and the Boardwalk area, plus Yacht and Beach Club, plus the Swan and Dolphin Hotels. You can also walk between Epcot and DHS, but most people just take the boat or Skyliner as it is faster and you will have already walked miles in the parks.
There are no walkable hotels from Animal Kingdom park, which is the furthest park out, but Animal Kingdom Lodge is worth a visit and has 2 good restaurants, Boma and Jiko plus the Victoria Falls bar. Since it's your first visit, save this one for another time as 5-6 days can be filled so easily with other things to do.
November is a great time to go. The weather is usually beautiful with low seventies to low eighties.
Xmas decor will be going up. The schedule changes year to year on who gets decorated first, and it is all gorgeous.
Adding park hopping to a 5 day ticket is roughly around $85, unless they've changed it. It doesn't look like anyone will be able to park hop by November so it's sort of moot right now. So, I think you will be fine with one park a day for your first visit. I've got my park reservations in place already for November, even though I'm possibly canceling. So as soon as you can book, also make your park reservations - this isn't going away this year and is a new necessity. Also, since the price of tickets is front loaded, adding a day to your 5 day ticket is quite inexpensive at $15 to $20. (not using exact to the penny numbers as I can't pull up the website right now and ticket prices vary slightly based on the day chosen.)
I wish I could describe WDW to you as it was. But now, it's going to be different. A friend was in MK yesterday for the passholder preview and loved it as they walked onto everything.
@snugglebug is also there now. Although no crowds sound optimal for touring, part of the vibe is families having fun - I think I like a certain crowd level, even though it means waits for rides and attractions.
