I think everyone should make their own reservations. As someone who has put together group hikes, it's like herding cats. And when you make reservations online, you have to pay at that time, so that shouldn't be on you Cranky Bear.
Since we are hanging and most won't be using the shelters, I'm wondering if there are pay boxes at the sites and we can just pay in cash when we get there? Something else to investigate.
I've stayed at the shelter area closest to Ohiopyle. Having firewood there was great! I also lost my big toe nail on that part of the trail. Some steep ups and downs and my trail shoes were more like tennis shoes with lots of stretch and my toe kept hitting the front of my shoe on the steep downs. That was the last hike for those shoes!
