We are traveling to Rome in the beginning of March. There are 9 of us going, 5 adults (two are young adults) and 4 kids (ages 11-17). We have 6 days of sight-seeing, is 6 days in Rome too much for that large of a group? Should we consider day trips we can take via train? I'm hoping that COVID starts to decline before we get there and restrictions might be eased just a little. BUT even with current restrictions in place, I feel like we could still see and do quite a bit. (We are all vaccinated and know we need masks).
On top of those questions, any help with the following is greatly appreciated:
Getting from the airport to our AirBnB (which is in the San Saba neighborhood, not too far from the Circo Massimo) - I'm thinking that hiring a car service might be the best bet, but would love any suggestions.
Getting around Rome with that large of a group

Any other general tips are great appreciated.
