They had better, since you probably paid a standard rate as a penalty. I would immediately call the hotel and have them fax you a copy of the bill.
If they hesitate in any way whatsoever about giving the points, I'd dispute the charge with the credit card company in return. One good turn deserves another!
My Hilton pet peeve of the week: the local Hilton that I'm crashing at now not only charges a $50 fee for checking out on a different day than the reservation, but has instituted a 1-day cancellation policy. In return, I book every day I am there as a separate reservation. If I need to leave on a Tuesday ahead of schedule, I merely cancel my Wed and Thu reservations.
It confuses and frustrates the minimum-wage flunkies at the front desk, but they'll never hit me with a fee!!!
(This trick can be done at a Hyatt for you Diamond members and you can go home with a bottle of wine for every day of the week)
