We'll be visiting Spoleto as part of a day trip and wondering what's the best way to see the sights with a 3 & 5 year old. We'll have our rental car that we'll be driving into Spoleto- but was wondering where to leave the car to get to the aqueduct, the roman theater, and also lunching near the arch (on Via Arco di Druso)? Are these all within walking distance? I know parking is tricky..so trying to figure out the best way to see all of this, with the least hassle. Thanks!
