Who wants a know-it-all on a holiday? Some of the things about exploring on a holiday is that you learn these bits and incidentals about the country’s past on your own.Another thing gunky about escorted tours: You seldom dodge the itinerary. If you come across a beautiful Monet or a piece of jewelry you’d like to buy in the souvenir shop, you can’t get the name of the piece if you’re hurried along to see the next thing or hear some next tale behind the sights today.
