I sincerely doubt it. Why would they schedule a bus to run at 2am to pick up the 4 people from that specific hotel that went to that specific HHN night and stayed to the end? Or do they just try to pick some arbitrary earlier time that people will be done with HHN? And when is the bus ride over TO HHN - before 6pm, at 8pm, etc? It'd be a waste of money for off-site hotels to try to do it, and inevitably no one would be happy with whatever timing they decided upon.
