Exactly what Anne said. Disney can't get enough drivers to drive the buses they have now. Standing in buses is not all that unsafe, for heavens sake.
But, again, I'm still curious as to why the seating on the buses has changed in the past several years. The buses used to have rows of double seating, on each side of the aisle, with some along the side of the bus that faced each other,with spots for wheelchairs,
ecvs. But, for the most part the seating was in rows. Does anyone know why the change? It was much easier standing on those buses. Sure, perhaps the new buses have more standing room, but with this type of 'open' space, there are rows of people, three deep, that are standing...not very well balanced if you ask me. At least with the old buses, if you were standing, you weren't stepping on people's feet, you were facing someone's less than attractive areas dead on...there were many more handholds to grab.
Wish those buses were back, but maybe they all died a natural death.
