I found that out, too.  So I called to ask about losing hotel reservations and was told I'd be compensated.  At least I never saw such rough treatment of a passenger.  Anyway, I made my reservation before the incident because Hawaiian had a much better route for my needs  that didn't require a red-eyed flight.  United had such an indirect connection to San Luis Obispo that I couldn't even buy a round trip ticket, only multiple-city which made it so much more expensive than Hawaiian.  So all in all, Hawaiian provided a much better route service.
