I am planning 8 nights in Italy with 6 adults and my 2 small children. I lived in Rome for a semester in college and feel like I can get around OK but I'm curious if anyone has any experience with taxis or public transport and car seat usage. I'm organizing a car service to/from FCO into the historic center (Largo Argentina) where we are staying and I'm wondering if I need to bring a car seat with me for those rides or if those can typically be provided by the transport company. I'm also curious about travel strollers and buses (we will be taking the bus to/from Termini for a mid-week overnight in Florence) and whether or not there are designated stroller areas on busses (like in London) or I'll be opening and closing it up frequently. Finally, I'm looking for family friendly tour guides or companies for a few organized tours for the 8 of us. I'm seeing that in the Colosseum most tours say age two and up, so I reckon I'll have to hire someone for our little group to see the Colosseum and Forum and I'd like to do the same for the Vatican and Vatican Museums. Tour guide recommendations for the family in Florence also welcome!
Any family-friendly trip planning advice would be greatly appreciated!
