My take is that you paid for a certain service and of that you didn't recieve fully what you paid for. You should recieve at least partial reimbursement. If none comes in a timely manner, I'd look into seeing them in small claims court.

If the outfitter had a guide that failed to show up, then the outfitter still has the responsibility to fill that spot even if it means the owner of the outfit shows up and performs the task of your guide. You paid for a guide, you didn't have a guide, hence the outfitter failed to come through 100% of the services paid for. He owes you.
