I stayed at ASMU and never had a problem with buses. I'm always confuzzled when I see people talk about how *horrible* it is to share buses b/c we stayed at ASMU so we were the middle stop and it literally took about an extra 2 minutes to drive next door and pick up the people at ASMO; granted, it was my first stay on Disney property so I have nothing to compare it to BUT I will share my Pop vs. AS bus story: since the *** are so much smaller than POP, the lines for the buses at ASMU were never very long. Maybe 20 people TOPS and that wasn't the norm, it was usually under 10-15 people in each park line. So we always got on. Well we went to Universal one day and took a shuttle which stopped at several different resorts, one of them being POP. I was taken aback by the HORDES of people standing in the lines for the park buses. I thought for a minute there was a fire drill going on or something, there was so many people, lol. So it seemed to me that with that many people wiating, you might have to wait for several buses to go by before getting on one.
