Redeeming long stays is not always possible as the number of points required are generally pretty high. Offers like this one help in that case. When you are redeeming your Hilton Honor points, you will get one night free for every 5 reward nights booked. i.e. you use points for 4 nights and stay for 5, use points for 8 nights and stay for 10 and so on. This needs to be an all point booking.

Hilton 5th night free is only applicable on Standard Room Rewards. There is a cap of maximum 4 free nights (total 20 night stay) for 1 stay under this offer. Available only for Silver, Gold and Diamond Elite Members.
