1st time coming to Rome in the summer love history and sight seeing seems to be a lot off diff types of coliseum tours what one do people recommend for soaking up the history and learning.

We are looking for an in-depth (live, not audio) guided tour of the Colosseum including Belvedere terrace, imperial balcony, arena floor, and underground. I can’t figure out if each area is a separate ticket or not. I found shore excursions from Civitavecchia that visit different parts of the colosseum like seating area and terraces, or the arena floor and gladiators gate, or underground, ranging 85€ - 150€, lasting 7 hours. All include palatine hill and the forum. We’re not interested in the other sites in the area, as we visited them on a prior visit. We just want to spend a few hours exploring the colosseum. I appreciate any guidance or recommendations you can give in figuring this out.
