My husband ended up being far more worn out than the rest of us because of how much he had to carry. Now he's tired, cranky and sore, and still saying I was unreasonable to expect him to carry all of that on his own.
When my husband was packing, I reminded him what he needed to bring and told him he's way over packing to be practical. He insisted he needed everything he packed as well as insisted on using the roller suitcases as carrying a backpack is too embarrassing for him.
