They ask you to wait 10 business days before requesting. Some hotels are incredibly quick and it happens the next day. Other hotels just never ever post without a call.

If you are really desperate for some reason (for example to book a trip or qualify for Gold/Platinum) then you can likely call and submit your receipt to be credited. I have had mixed luck with this.

Sometimes they are strict about every detail and sometimes you just get credited in minutes.

YMMV.
