May have a chance to transit DOH on an upcoming Saturday between 8AM till Noon or so.
Flying QR-C ...so, i guess I can buy can access to A.S lounge (if I choose to).

Can I buy access after verifying if the sleeping rooms are available (whenever I reach DOH)? Not sure how good the chances to find a sleeping room in that time of the day.

(website is quoting a cheaper 137 USD price in "manage my booking" if I buy ahead of time,,,..but do not want to commit without knowing if the room is available)
