We did PP Concierge this past Summer and really enjoyed it. We were able to utilize it fully as we were there during a time of maximum operating hours and very warm temps. We would come back daily to the hotel for a swim and afternoon snacks, so got to get more of our money's worth out of it. We had a cabana/poolside patio room so the access to swimming was perfect.
Since you are planning for early Dec, it may not be as favorable of an option, as you may not come back as often mid-day and the concierge poolside room may not be a perk if the weather is not warm enough to swim.
We really like the PPH, no matter what room we stay in (standard or concierge). However, I have heard the the new DLH rooms are pretty awesome, too! I think you will do well whatever you decide!
