Ok, my husband, daughter (15) and I are in Rome June 8th. By happenstance, I was able to get 2 (full adult price) tickets to the Colosseum underground (that was all that I could nab). So planning on 2 of us going to the underground (my daughter using a full price and one parent), while the other hangs out. Goal would be to get the third person a ticket to the regular colosseum experience with arena and meet up after the first two finish the underground. So assuming I have 2 tickets at 2:15 for the underground, what entrance time should we get the third ticket for?
Thanks much in advance!
