While travelling in England a few years ago and on a tour bus to Bath, a mother and daughter asked how i knew so much about where we were going.. Read a book I said. In this case a travel guide.
Might I suggest some of our posters do the same!
Buy a guide, sit in Barnes and Noble and read theirs if you don't want to buy,or go to your library. My wife tells me the most popular re-sale books in our library are the travel guides.
Sure some of the facts are wrong or outdated but you get a sense of what you should see and do in that part of the world. Then I bug the TA experts!!!
I keep my guide on the coffee table for tv commercials!!
See you at the bookstore
