Think comes to vibe you are looking at experiencing.
Places stayed -
Poly, the grounds are awesome, we stayed in concierge club level that offered afternoon booze and food, it was nice touch, but worth the extra$$$ prob not. The concierge room does provide a kick %SS view of kingdom fireworks and water parade. resort has nice pool and nice walking, easy access to monorail,
Depending on time of year, fort wilderness campground, we had our camper, but they have cabins, so its like VRBO but disney style. @ christmas and halloween, campsites are decorated by camper which is fun nighttime activity to walk around, rent a golf cart or bikes. Overall campsite is dog friendly (not sure about cabins). from transportation perspective, you have busses or can hop a boat across lake to front of MK to catch monorail.
Also stayed at art of animation, over run with rug ratts but if looking to immerse yourself in charter themes, its pretty cool. pools are nice and have outside bar.
Coronado - more laid back, has more of a business type feel with conference center.
