You can book DLR on points at 11 months out. However, they don't always have the rates released yet. For example, for my upcoming trip to the DLH in January, I was not able to book that trip until somthing like late August or early September. I called my rep and she called me as soon as they had released room rates so I didnt have to keep calling. DL doesn't release room rates to anyone else earlier either so its not like the place will be sold out before points are released. You can book on ponts at the same time cash reservations/packages are released. For an August trip however, I wouldn't tarry too much. Those reosrts sell out all year, peak seasons and weekends in particular. All 2008 rates are out at this point so people have been booking for your time frame for sometime now.
