We have stayed at AOA in the suites and we enjoyed the extra space, table, fridge, microwave etc., All Star Music has a cheaper suite.
We have done two rooms and that was good also.
The only way we have been able to cut down on travel time is to drive ourselves. If you get to HS or Animal Kingdom very early and a little before it opens you can park near front and is an easy walk to front gate. We do not drive to MK because of taking the ferry.
We have stayed at the fort in our camper and it is nice to take the boats. Its a nice change from the bus. The campground is so big they do have to run bus inside to get you to were you want to be, swimming pool, boat dock, trading post, etc., Other wise everyone would have to rent a golf cart or walk a long ways! We ask for a campsite near the lake in loops, 100, 200, 300, 400, 700 to eliminate the need for taking a bus to catch the boat to MK and Epcot. That helps some on this. I'm not sure if Cabins are near the boat dock. But that would be my first choice or near the pool with children. I would want to eliminate taking a bus one place or another.
