Just like buses at every single resort at Disney.
Good if you are fortunate enough to walk up and catch a bus at is comes
Bad if you are unfortunate enough to walk up and watch the bus as it's pulls away.
The 2 above situations could happen to 2 guests at the same resort on the same day at the same bus stop just 5 min apart from each other.
They'd come back with 2 extremely different reports on bus service.
