We are going on this tour in Oct 2024, our first Tauck vacation. Any tips and thoughts welcome. Specifically, wondering about the time in Rome. General itinerary says "after-hours guided visit to the Vatican Museums and the Sistine Chapel (subject to availability" When will we know if available for after hours tour? I don't want to miss seeing them. Also, do you actually go into the Forum and Circus Maximus? The itinerary is unclear if you are doing a outside walk around or actually going in. Appreciate anyone that experiences this tour earlier this year and can report back! TIA
