Welcome Susan
I am not sure which Italy tour your interested in, I have been on the highlights of Tuscany tour and can really recommend that tour. At 62 you will fit in just fine..I have been useing JY for 10 years, any other questions just ask.
Great tours you see and do so much in a safe secure way, more ladies than gentleman per tour group. Really look at what's on offer for the tour, what's included or not included are there extra excursions you can do, then book it and then write a review when you get back.
Have fun
Cindy
