I bought my share of DVC with the idea I'd be using the points a lot for DL. I have used them once so far and will be using them for another trip in November. Both points trips will be at the DLH, and in between I got a pretty good package deal to stay at PPH.
DLH is the cheapest for some reason with points even though with cash PPH is cheapest. Sounds like for some reason DVC demand is higher at PPH, but I'm not sure why... I loved all the Beach Boys music, but overall, loved DLH much better. It is closer to DTD and is steps away from the monorail station which will take you to Tomorrowland. The monorail will at times be only for hotel guests and runs during EE too... And the TL stop is right at the subs.
Points-wise, you can stay @ DLH for 19 points a weeknight during value season. Peak season the same room goes for 26 points. They are good about upgrading DVC members from standard to premium view if there are rooms available. That happened on my first trip, although for my upcoming trip they didn't have standard available within the DVC allotment (maybe they'll upgrade us to concierge?
). PPH goes from 20 to 31 for standard from value to peak, GCH 24-33 standard room. Incidentally, the GC entrance to DCA is good for all people staying on property, but obviously works best for those staying at GCH. It also has an entrance right into about the middle of DTD.
