We wouldn't have it any other way, want to be in the thick of things 24/7, alot of options on resorts out there at various prices. Hope you have a great stay!
It really depends on what your budget is and the number of people in a room (and any children's ages). Onsite choices could be any level of resort from value to Deluxe Villa (a.k.a. Disney Vacation Club).
Value sleeps 4 people plus 1 infant under 3. I believe most Moderates are the same with the exception of Port Orleans Riverside which can sleep 5. Deluxe and Villas (studio or 1 bdrm) can sleep 5. Villas also come in larger configurations.
I just stayed at Pop Century (value) for the first time after staying at 2 Villas (1 bdrm both times) and loved Pop! You may request connecting (door in between) or adjoining (side by side) rooms for each family so you can be close to each other. I believe you can do this at all resorts.
Another option might be to look into renting points for a Disney Vacation Club resort. It's not for everyone but can make the cost of those accommodations more reasonable. You can find info on that here.
I have never planned a trip for offsite, so I can't comment on it, but you can find info here.
