great choice for a tour, I went on this a few years ago, don't worry you will not be on your own unless you want/need to.
this is a great tour as it's not to far and it's not to hectic so a good balance of things to do but not being on the go all the time.
A nice hotel but be warned the room vary, I was in one that looked out to the beach but it was so small, but it's only to wash and sleep in for a week so I just got on with it, others had really big rooms it's the luck of the draw, there is a lift, and a nice sun terrace at the very top. the only tour I did not do was Elba? Perhaps as I am not a lover of boats! but I spent a very pleasant few hours in the local town (short walk away) and had a few hours on the sun terrace.
I am sure I would of put a review up in the review section so have a look and see what others have said. if I can help with anything else then please just ask.
