Mine always seem to post ok, but I always check when the stay posts to the web site.
By looking at the stay detail for a stay on the web site, you should see an entry for MC stays. If that entry isn't there, then you need to call.
To get there, login, go to 'account detail', then choose 'hotel stays' from the pull-down menu. Then click on a hotel name for the details for that stay. Just like with the old Amex promotions, you will see a line with "MasterCard Charge" for properly credited stays. If it's not there, then it wasn't properly registered.
