I just stayed at Pop and it was a wonderful resort, but one of the things I didn't like was the sheer amount of people because of the size of the resort. It was crowded on all of the busses, in the food court, and the store inside of the resort. The transportation was good, but I believe that the bus transportation at POFQ is also good.
We went in July during one of the most crowded times of the year, but others have said that this resort has been staying full because of the newness of it.
If your husband dislikes crowds, you could use this as a reason to go to POFQ because it is a much smaller resort. Pop has 2880 rooms and POFQ has 1008 rooms available.
I also have an 11 son and he enjoyed staying at Pop, but is excited that we are going to try POFQ next year because of the slide.
