A year ago, I would have said "never". In the past several months, they've been depositing a few weeks here and there---and some good ones too. I personally saw a unit for President's Week in 2009 (though I forget if it was a 1BR or a 2BR).
Wyndham's June '09 deposits just went in today. I didn't see any Bonnet Creek inventory, but I also only had a mediocre trader.
