This is a really tough choice for those of us with families larger than 4. Your options generally are larger spaces off-site, choosing a cabin at FW, renting points for a 2 bedroom DVC, or booking 2 rooms onsite generally at a value resort.
My family of 5 does well in a cabin, and we love FW, but the sleepers have to share a double bed in the bedroom with two bunks, and there's a double fold-down Murphy bed in the living room for two others. I usually recommend loop 2100 since it backs up to regular camping loop 1100 with its comfort station and laundry in case there are any bathroom challenges.
At the DTD GuestQuarters, you have the option of enights (if there ever are anymore), but not EMH.
The DVC properties are lovely, but at $10/point it's not always economical. You can check the rent/trade board here to get an idea of points needed at the time of year you plan to visit.
