We did Conc. at PP last fall. We wanted to stay on site, with the 4th night free. Our first choice was DLH, but it was full. We had to choose between conc at PP or a standard room at GC for roughly the same price. We figured in the conc at PP would help save us a little in th end.
We never used the DVD's. We were never in our room long enough to watch tv. The breakfast was a good way to start the day. Dh, me and our kids only made it to the evening hot app./ snacks once. My FIL and MIL did eat there in the evening a couple of times. We did take advantage of the pop/juice/water. We would take with us to the park and in our room.
You also get priority check in which is nice. When you get to the hotel, dont wait in the check in line. Let them know at the little desk to the right of the door, that you are a conc. guest. They will lead you to the lounge. YOu can have drinks and snacks while you wait to get checked in. YOu can also wait in there and watch tv until your room is ready. They will also help you with PS during your trip.
