One problem with having buses as a backup to the gondola system:
Say you are hanging out with Nemo and Friends at the Seas pavilion. It's late afternoon and your "precious angel" is starting to get a little cranky so you decide that you want to head back to your family suite at the Art of Animation resort. You pick up your stroller from the stroller junkyard and walk all the way through Future World and through Canada and Great Britain to get to the International Gateway Gondola Station. In the meantime, the skies decide they can't hold any more water and it starts to rain, and rain hard. You are getting aggravated because your $5.00 poncho isn't holding up to well and your "precious angel's" attitude has taken a turn for the worse. You finally get to the Gondola Station and you see a sign that says "Due to Inclement Weather, the WDW Gondola System is not operating. Please use bus transportation instead." Now is when you realize that the closest bus that is going to the Art of Animation Resort is at the front of Epcot.
@KATIEBUG101 will not be happy!!!
