I have travelled a lot in my lifetime and I found Marcello to be the BEST Program Director/Tour Guide in all my years of travelling! You can tell her loves his job. Never a dull moment. He must have done this tour tons of times and you think he would be bored with it. But no! You can tell he just LOVES to see people enjoying themselves and getting educated at the same time. He makes sure that everyone is happy and takes care of any problems you may have. He organized a little side trip for me, which was very much appreciated. I definitely will recommend him to anyone I know who is planning on visiting Sicily.
