if you want to use my diamond account for your feb15 stay youre more than welcome to.....or anyone can for that matter
But the only way that works is if the reservation is in cash (and the person actually staying there pays you back) or it's in cash and points (and the person actually staying pays you back the cash and the value of the points), correct? No way for the person staying to use your diamond number with his points/free nights, correct?
