So on the official website - www.coopculture.it/en/ticket_office.cfm there are options for buying tickets for the Colosseum. So the standard ticket for the Colosseum ALSO includes the Forum and Hill, is that correct, for 12 Euros (+res fee)??
However, the ticket for the Colosseum, underground, third ring and Belvedere does NOT include the Forum and Hill, is that right?
What ticket should I purchase if I wanted to do all of the above? Is the underground, third ring etc. worth seeing?
