You spend a lot of time while the tour company coordinates travel for multiple tours. For example on last day you leave at 3:15 travel to Pompeii to meet a group that has toured there, then to Naples to pick up anoter group that has toured Capri. You finally get back to Rome about 9:30 that night. There are good parts. The Pompeii trour is great and the accomodations in Sorrento are excellent.
One of best tours I did while in Italy
