Just back from a 4 day trip to WDW. The parks were very crowded and as expected, the buses to and from POP were also at capacity. There were multiple times where we had to stand on the bus which was not a problem. My gripe is the parents that allow children to sit in a seat while there are older folks or parents holding children and having to stand. Where are peoples manners? Would it be too much to ask for parents to have a child sit on your lap and allow someone else a seat? Also, with the buses filled to standing room only, the bus drivers could be a little more gentle on the brakes.
