Tummy,
Are you an Hhonors member? Hhonors members are supposed to receive complimentary late check-out when available. If they have availability "for sale," they certainly should have offered a comlimentary late check-out for hhonors members. If you are an hhonors member and they had availability yet insisted on charging you for it, you may want to speak with the hhonors manager or call the hhonors desk. On the other hand, if you are not yet an hhonors member, sign up, it's free.
