My cousins took an Italy tour with them a few years back. They were in their late 50's and went with a couple in their early 30's. It was their first European trip. They only had great things to say about it. You have to like being with a group, touring as a group, eating as a group, etc. Free time was limited. Still, they loved it!
I live in NJ and I remember hearing their ads back when I first moved here as a teenager in the 1970s. Over the years I've heard people talk about Perillo Tours in a very positive way. As the previous poster says, you have to like group tours...but maybe you can bring a lot of your friends and make your own group!
