Regarding the buses - the are no better or no worse than the buses from the other resorts. AKV is located further out from the parks except for AK of course. If you were heading to one of the other resorts, you could take a bus to AK and then hop on a particular resort bus there. We did take a cab once when returning from a late dinner at another resort. It was very reasonable and fast, so that is always an option for you too.
