Hello. If you buy the ticket for Huchuy Picchu, they allow you to see a part of the Citadel. However, we want to see the whole Citadel. So we are contemplating buying two tickets. How long do you think it will take to complete BOTH of these circuits? We will be going at a normal pace, probably a little faster than most. Need to know soon so I can finalize some things. Thank you!!!
