I don't know what time of year you are traveling but be aware that the All Stars often get large groups of kids for the various events at the sports complex. Don't know if that matters, as far as I know AofA does not. We loved the ASMu suite over two standard rooms as we used the kitchenette every morning for breakfast which was far easier as everyone could get ready and eat at their own pace, and of course much cheaper than the food court. With a group including teens I would imagine that would be a pretty significant savings! And even though ASMu is a large resort the family suites are located in the Preferred buildings close to the main hall, food court, bus stop, etc.
We never had any issues with the bus service, I am one of those who happen to like the way the bus stops are set up at the value resorts with one bus stop and an orderly line.
