In my two dozen stays this year, only two have not posted within the normal timeframe. Both of these were Reno Hilton stays with a sub-$49 folio, which still necessitate manual credit by HHonors due to the hotel's policy of refusing HHonors credit on these rates.
None of my stays within the timeframe of June 9 to the present (11 stays total) have had delayed posting. In fact, of my three weekend stays, two (Friday night and Saturday night) have already posted to my account.
