I was able to use my two remaining DSUs to a future stays without enough points in my account.

Currently I have 10,000 points but needed 50,000 points to do a C+P in November, so I called GP and asked the agent if I could book C+P without out points and apply the DSU. She said as a Diamond member, she can do that.

I got confirmation for the two dates and email shows Park Suite for the selected dates. She reminded me I should have the points in my account by November 1st. (stay is late Nov during Thanksgiving).

My questions is...

Is this a known practice? Was this done by error? The agent said, let's try it and it went through.

If it's an error I would rather transfer UR points and have the points in my account and not waste my two DSUs that will expire after tomorrow.

(If this is legit, I would rather not transfer my precious UR points and get points through future stays and Hyatt credit card spends).
