I just returned from WDW (May 3rd-10th). On three different mornings the buses filled, so I purposely waited for the next bus, to make sure I would have a seat. On all three mornings an ECV pulled up with their small party (two-four people). They were boarded first (which they should be), but then there would suddenly be a mad rush with people jumping on through the back door. On only one occasion did a driver stop them and make them board through the front door, behind those of us who were standing patiently at the front door waiting. On one occasion the driver was reaching to push the button to close the door, when a large group came running up and started jumping through those back doors. The driver hesitated for only a moment, before he went ahead and waved them on, while the rest of us (who had been waiting there much earlier) were stuck waiting in line by the front door. So obviously the drivers saw what these people were doing, but chose not to say anything. If it had happened just once, it wouldn't have been a big deal, but this happened on three different mornings. Have the rules changed, as far as nonwheelchair parties being allowed to board through those back doors? It was really annoying to those of us who had been there a long time and were trying to board through the front. I was at POFQ, by the way.
