Beginning December 7th, you can be picked up inside the four theme parks and reach your destinations faster.  There is a hitch though.  If you are a passholder or a castmember, you can only purchase the one day pass.  The only way you can purchase the multi-day pass is if you are not one of those people.  More details on this will become available towards the launch date.  Thanks to wdwnt.com for this breaking news. http://wdwnt.com/blog/2016/12/breaking-walt-disney-world-adding-express-bus
