Lisa:
This is a tough call because I'm a big fan of
Fort Wilderness. Although two rooms at a Value Resort may be cheaper than the cabin, keep in mind that Disney does not guarantee connecting or even adjoining rooms. (When we took the grandparents with us a few years ago, we had asked for connecting rooms but had to settle for adjoining rooms which were next door to each other but without an inside, connecting door.) While the cabins guarantee you will all be together, they also come with a full kitchen, a large living/dining space, a deck with grill and plenty of space outside for kids to run around, bring a scooter or get some fresh air. Two rooms at the Values will only come with a small refrigerator. Boat access to the Magic Kingdom provides a ride all its own, and also in November, Fort Wilderness beckons fall with campsites and cabins decorated for both Halloween and Christmas, a unique feel different from any other resort.
Because cooking meals in your cabin can reap the savings you'd get from booking the two Value rooms, the only thing that would sway me to recommend you go with those two Value rooms over the cabin would be if the three kids in your group were
teenage girls. Otherwise, I'd stick with the fort.
Wishing y'all a magical vacation!
