Okay, that makes sense, thanks.
Incidentally, one way to get a hike at Havasupai is to show up at the parking lot, ready to go, with cash in hand. There are generally groups going who have had cancellations, and if they are willing to take you on, then you have your hike. This happened to a group I was with a year and a half ago. A couple approached us in the parking lot as we prepared to leave and asked if we had any free space on our permit. The permit holder said, yes, and allowed them to go with us.
