They divided the crowd into several groups, each traveling to the site via a van that held about 10 people.
The price was $90, plus an $8.00 Navajo Park fee and other fees, totaling $97.50. They tell you in advance to arrive 1/2 hour before your tour.
I purchased a ticket 2 weeks in advance and I was glad I did as there was only 1 ticket left for my 12pm tour on the week before Thanksgiving. My tour began meeting at the Antelope Canyon Tours located at 22 So.
