Yep that was teh 1st thing that came into my head. Big deal no printer or it doesnt work, check-in anyway and click 'Print' you are now Offically Checeked In and stop by a counter kyosk to actually print it up at the Airport, Minus 1 pt to the OP on this

As for the Hotel, IMO they owe the OP for not having made the wake up calls and not say 5k in pts either. I see the Wake-up Call as an Essential Service that should be performed by the Hotel. which has nothing to do with if a person should have a backup in place.
