Keine-Warteschlangen-Tickets für Chichén Itzá Cancún

It was not clear as to where to go to get our tickets. None of the 'officials' were aware of the 'special ticket' and we moved from one place to another. Eventually all worked out as we were treated kindly by all.
Signage is needed those assisting viistors need to be told about the pre-booking system.
Works well in terms of skipping the linee, but it took us LONGER than if we had bought a ticket there. However, this was because we arrived early. Laetr in the day it would have been a great advantage to have pre-booked.
