I am a single man traveling alone. I want a group tour of the Colosseum and possibly the other areas some tours also go to outside the Colosseum, nothing too private, so that I won't feel retarded in case I can't think of much to ask my tour guide.
Which of these tours is most likely what I want?
Walks of Italy - 3 hours 45 minutes, $103.99 - VIP Colosseum underground tour with Roman Forum and Palatine hill. (I already reserved this tour but I must have been too tired when I did, I missed page 816 of Rick Steves Italy 2017. Now I doubt I made a good choice. They give full refunds if you cancel far enough in advance, otherwise I wouldn't be posting this).
Europe Odyssey - Underground Colosseum Tour. 3 hours, 30 minutes. Only 75 euros. Why go on the walks of Italy tour if this is the same thing but cheaper?
The Roman Guy - Colosseum Dungeons Tour, Roman Forum and Palatine Hill, VIP ACCESS TO THE COLOSSEUM UNDERGROUND, ARENA FLOOR & THIRD TIER. 3 hours, 30 minutes. Appears to be the same sort of tour as the two listed above, just a different tour guide.
Through Eternity tours - VIP Colosseum Underground Tour, Third Tier, Roman Forum & Palatine Hill. Website gives most detailed description. 119 Euros, 5 hours. Length of time doesn't bother me. I do like history. Perhaps the most detailed tour. Normally I am very cheap in general but if a tour is worth it, I guess it is worth it.
http://www.coopculture.it/en/colosseo-e-shop.cfm - official website that seems to sell the cheapest tours. Does not go outside the Colosseum. Would I be free to wander into the Forum or palatine hill unguided? I guess you would separately buy the entrance ticket + the tour tickets on the same site. Seems to be separate tours for the "Individuals guided tours" and the "Colosseum, Underground and Third Ring tours". The later tour lasts 1 hour and 30 minutes, the same amount of time The Roman Guy says they spend overall in the Colosseum.
