I did this once.
We were put on to a large bus. We had to wait until the bus was full, which was the better part of half and hour. We stopped at six resorts before we got to the one I was staying at.
A kid puked.
Several other kids were crying, they were hungry, or tired, or stressed, but it got on my nerves.
One couple was arguing the entire time, it was loud and obnoxious.
It was aver an hour and a half from the time we boarded the bus until we were dropped off.
Once was enough, never again.
