Myself and 3 others in my group would like to take guided tours of the Colosseum (preferably underground portion as well), Roman Forum, and Palatine Hill. From what I've researched, these are all typically included in the same tour. Is it worth it to pay the extra for the underground/VIP tour? Aside from WalksofItaly, are there any other good recommendations?
We would also like to do the Vatican tour (Museums, Sistine Chapel, St. Peter's Basilica). I noticed that you can book a guided tour directly through the Vatican website, the only downside is it looks as if you can choose from either the Vatican museums and the Sistine Chapel, or the museums and St. Peter's Basilica. Any ideas on how I can include all 3? Any help is appreciated. This vacation planning is getting a bit overwhelming!
