Hi Janice,
Honestly, I'd do 2 rooms at
Pop Century instead. I know this wasn't one that you suggested, but I figured I'd throw it out there anyway. Pop Century is the "Top Pick" for favorite Value Resort by the Moms Panelists. The theme is great and it has it's own bus route (it doesn't share with the All-Star Resorts so you generally spend less time on the buses).
My family stayed in a
Cabin at Fort Wilderness last fall. There were 6 of us in there and it was a tight fit. In our case, there were 2 adults and 4 children. For one thing, there is only one bathroom, which can be a challenge with showers, etc. In addition, the bedding situation left a lot to be desired for us. The bedroom in the back has a double sized bed and twin bunk beds (an arms length away from the bed). The "murphy" style bed in the living room is also double (full) sized. While the Value Resorts also have double beds, I believe you'll feel less crowded with 2 separate rooms. I just can't imagine staying in one of the Cabins with 4 adults and 2 kids, I'm afraid you'll feel like you are on top of each other. At least with 2 separate rooms you can have a little bit of privacy as well as 2 bathrooms. In addition, we found the need to switch to an internal shuttle after taking a regular bus to be a bit of a hassle for us.
All Disney World guests are welcome to enjoy Chip 'n Dale's Campfire regardless of whether they are staying at Fort Wilderness. So, you could always just head over there one evening to check it out and walk around the Fort for a while. The setting is beautiful and definitely worth exploring.
My kids much preferred the large icons and overall atmosphere of the Value Resorts over the Cabins.
Hope this helps and have a wonderful vacation,
Kaylene
