wheatley, to each their own, if you opt to DIY that's great but it has no bearing on what someone else signed a contract for. They chose the guided/outfitted route and IMHO have every right to expect what they contracted for an nothing less.
I've done as many if not more DIY trips as I have guided ones...I was in the biz for many years in Alaska prior to relocating to the lower 48. There is a huge difference in a whitetail or elk hunt one can jump in the truck and drive to in a few days and a hunt that takes place 25 miles from the nearest dirt landing strip.
