Hi. My husband and I are first time Tauck Tour travelers and will be going on the June 3-15 Amalfi Coast tour. Between now and then I will be taking advantage of your generous information and tips by posting my mostly naive questions. I have done a little perusing and have seen the term "Green Book" several times. In speaking with two different Tauck customer representatives, neither could tell me what a Green Book is. That's my first question. What's a green book? Next, Is there a suggested effective way to maneuver through the site to learn from others? Last for now but not forever: any insider tips for a couple of newbies? Thank you so much. This community forum is extraordinary.
