Q: We’re wondering what you’ve heard about Perillo Tours. We were thinking of taking a trip with them to Italy. Is there a place on the Internet where we can read opinions posted by past customers?

A: I doubt that Perillo would have stayed in business for so many decades were they not a good company, although I’ve never traveled with them. But I’ve also never received any complaints, so I think you can book with confidence. You might want to check out postings about them on tripadvisor.com. Just search under “Perillo.” I think a lot depends on exactly who your guide will be. Whoever it is, you might consider tipping your guide (and your driver) generously at the start of the trip rather than at the end. I always find this tactic works wonders.
