The original bus stop was never more than an afterthought. There were no seats, no shelter, and wheelchair access was abysmal at best. The new stop is attractive, sheltered, provides easy access to all, and has seats.
The old bus stop is now closed, and all signage has been removed. If you go there to wait for a bus, you'll be out of luck. Technically speaking, buses should no longer be going down that way, but rather up on the other side of the stairs, closer to the porte cochere. (Disney goofed on the bus stop, and has us making an illegal left turn from a right lane. Drivers not wishing to make this illegal turn are forced to go down the Mears lane.)
