Thanks for the info! Still flip flopping between two and three resorts at this point. Called the booking company, they said no problem, just list it on the separate booking requests and they will take care of it. I am planing for November of 2019, will submit the requests as soon as possible (11 months out I hear). Don't think we will use the pools too much, we typically hit the parks as much as we can. 9 nights is starting to feel too short, darn those budgets!
I am hearing a lot about how awesome AK is. A little reluctant to book an extended stay there because of the distance from the other parks. If I do, maybe towards the end of the trip would work.
I think that a three way split is going to be more work than you are expecting during a very busy time of year. Fall 2019 may be more crowded than normal, and when you consider the size difference between WDW and DLR, along with the size of all the parks, the differences are magnified.
Personally, on a first trip to WDW I would want something that is entirely different than what I could find in DLR, so I would choose Animal Kingdom Lodge for one of my resort stays. (I would not move, however I know you want to) and a monorail resort for the other. If you only need a studio I bet your 11 YO will like the Poly, and the DVC units there are actually in longhouses that are part of teh entire Polynesian Village, and not parked in the back. I also would consider BLT in the Contemporary. Stunning views, and you can walk into the MK. Transportation to Epcot is convenient as well, a monorail ride away.
AS far as location, there is not one resort convenient to all four parks, and AKL is not as remote as some people seem to feel, IMO. It is a stunning resort that offers a real respite from the parks and the over stimulation that is part of a WDW stay. While this lovely resort is a destination for visitors for meals, etc, it is nto the magnet the Beach/Yacht Club and the monorail resort tend to be, especially during the Holidays.
Whatever youi decide, please keep inmind that a first trip can me overwhelming on it's own, so adding a lot of logistics in regards to packing and moving may be a bit stressful. Or not.I pick one and stay, so I am biased.
