I was thinking of redeeming this award for 7 night and 120,000 miles. If I am correct, I have one year to use 7 night stay up to Category 5.

I called Marriott rewards center and they confirmed the following:

- I have one year to redeem certificate
- they can extend it one time for one extra year
- I cannot cancel certificate and get miles back
- No partial stays, have to use 7 night stay at one hotel
- I can pay the point difference to stay at higher category anytime

Just want to confirm this is correct in advance!

Thanks
