I do not disagree with the airline not seating them because if a emergency had occured it would have been difficult providing both the disabled and able passengers assistance.I would think that every aircraft and or airline company has a limit set of disabled passengers allowed onboard and that limit is based on safety alone.If the airline was told in advance of the size of the group and denied them seating then they should have compensated them for room and board if they were not told ahead of time then I feel no compensation is coming as it would be the responsibility of whoever put the trip together
