Thank you everyone for contributing your time and expertise to the forum. I am looking forward to your advice and experiences.
-The Background: My husband and I are flying in to Rome one day before meeting our RS Tour in late June. Our plane arrives from the East coast of the USA in the morning. This will be our first trip to Europe and only the third time flying anywhere for our children. Kids are 15, 12, and 9. We will not be using any sleep aides for our children and we are uncomfortable using sleep aides ourselves in case our kids will need us during the long flight. We had originally planned on flying first into Barcelona for a few days to settle in to Europe and get over jet lag but due to an extended school year we had to cut that out and fly over one day before our tour begins.
-We are staying in the "tour" hotel the night before, near the Termini. We have already booked a car service to pick us up from FCO and deliver us to the hotel.
-Our question is what should we (would you??) plan for that first day and the morning of the second (we meet the tour later in the afternoon of that second day)? We understand from reading here that we should be up and about outside in the sunshine. We do not want to go to the big tourist spots with the kids in advance of the tour. For example, we have read of many people walking to the Roman Pantheon, Trevi Fountain, or Piazza Navona on arrival day -- however we believe we are going to be seeing these things on the tour (and surely much more informed then we can see them ourselves) so we don't want our kids to have the "just saw this already" syndrome (we are anticipating and preparing for some jet lag crankiness). Also with such a short time in Rome it seems a waste to repeat sights.
We have a recommendation for a family pizza restaurant near out hotel for lunch - or even dinner if we are in a different direction at lunch time. We think a stroll to Piazza Venezia to see the Vittorio Emmanuel II Monument would be a good idea (close to the hotel) and then taking in the view of Rome from the top was a good idea (although is also listed on the tour itinerary for free time on tour).
We are open to any and all suggestions from the community on places to get out and walk from the Termini location for sights and/or for food - keeping in mind there are 5 of us. We are looking to fill arrival day as well as the morning-early afternoon of day 2.
