Jimmy1- In your post in the General Cruising section you asked about being able to Pompeii and Florence on your own. Read my review of our Freedom cruise and you will have your answer. Both of these are very easy to do on your own for about a quarter of the cost of the cruise line tour. Sorrento is doable too, as well as capri, but if you try to do them all you will be time limited. Read me review and then read the guide to train travel in Italy for details on how to get to these places. (Its the first post in this section of the forum). Then come back and ask addtional questions and we will help you out.
