As regards tour companies, my advice is to be aware that even top-notch companies don't always deliver what's promised and paid for. We took a 3-hour tour with Dark Rome in June called a "semi-private" tour of the Vatican museums, the Sistine Chapel and St. Peter's Basilica. They promised: "Early-morning access, thanks to our Official Partnership, means you will enter the Museums before they open to the general public so you’ll stay ahead of the large crowds." Not so much. Evidently there are MANY other "official partners" who were also there early. By the time we got to the Sistine Chapel, we felt like cattle being herded. I couldn't even turn around. And the guards don't let you stand in one place for more than 3 seconds. We'd seen it before, but our friends had not and I felt sad that this was their experience. Also promised was that "With 12 people or less per group, your visit will be intimate and you will enjoy a more personal interaction with your guide." Also not true. There were at least 20 people in our group. Our tour guide was great, a true historian and a Rome local. For the price we paid (around $80 per person), we expected to receive what was advertised. Maybe it will be less crowded when you are there -- I hope so!
