Maybe they should just extend the POP to all-day since it seems no one is going to stay there all day anyway. This would take away that feeling of "I've only got six hours to get my money's worth and I don't want to waste precious ride time sitting down to eat or shop."
They also need more options at the park. I remember Playland having a few Nathans and Burger Kings but little else. Maybe people would be more inclined to spend time at the parks if the meal options were a little more original than those at the local mall's food court.
