I want to hear from anyone who has done this. I probably should also contact the hotel ahead of stay to get an OK on it.

The hotel is DT Kuala Lumpur. I can book 5 nights and it costs the same amount of points as 4 nights due to the 5th night free feature.

We have a late night departure KUL-BKK, so it would be nice to still have hotel room well pass noon. We would need 4 nights anyway. If I book the 5th night free we can still have the room on our 5th day till we leave for airport and I just check out in early evening instead of the next morning.

Does anyone has done this before? Do you see any issue of doing this?

Thanks for your opinions.
