When we saw the Lower one in the fall of 2014, we just showed up and got in. When we saw the Upper one in June, we had a reservation.
We took a 61 day trip from Eastern Ontario, Canada to California, up to Olympic National Park, over to Vancouver Island, and back through Canada. I had reservations for everything I was able to get reservations for. This included campsites, tours, ferries, etc. It worked out very well.
They don’t charge you for the reservation at Antelope Canyon, but if you fail to show up an hour before, you will lose your reservation. We stayed at a campground in Page the night before, then brought the trailer with us to the canyon, and after the tour we drove to the Grand Canyon. They have a big parking lot with a special area for buses and big rigs.
