Will have one full day in Rome in August as day trip from Tuscany. We actually have 1 and a half - the half day we have booked a private guide for vatican museums.
So we have one full day after arriving into Roma Termini at 0835am. We hope to be picked up in a minivan (we will be two adults and three small ones (4,3,1yo), and then driven around Rome to see all the main sites - I think that the minivan/limo guided tour is definately the easiest way to go with the three little ones.
There are so many good companies out there but I was after experiences from anyone who did a similar tour with young kids who has had a particularly good experience with a particular company.
