It’s impossible not to love Switzerland. It has mountains, lakes, cheese, yodelers, dancers, drinkers and some of the most picturesque villages in the world. Zurich is the largest Swiss city, boasting a population of nearly half a million.

A bustling world banking center. Zurich has almost zero unemployment, and the people there are considered some of the most affluent in Europe. Of course, world-class bankers and smugglers keep their untaxed stashes in Swiss banks.

What do Franklin D. Roosevelt, Elvis Presley, Marilyn Monroe, Babe Ruth and Billie Holiday have in common? Not much, except that hotel rooms they once occupied in various American cities are still available for booking.

FDR: The Mayflower in Washington DC: President-elect Roosevelt stayed at the Mayflower before moving into the White House in January 1933.

Elvis Presley: He parked his blue suede shoes at the Best Western Trade Winds Courtyard Inn in Clinton OK. The country boy didn’t start out with the wealth of the Roosevelts, and in the days before Graceland, he stayed in more modest hotels.

The Old Western town of Tombstone is just an hour’s drive south of Tucson. If you grew up watching cowboy movies and TV shows, Tombstone is a familiar name. There were the oft-told legends of Boot Hill, Wyatt Earp and the famed gunfight at the OK Corral.

Many movies are about the 1884 incident. A favorite is the 1957 epic, "Gunfight at the OK Corral", starring Kirk Douglas and Burt Lancaster. John Ford also adopted the story for his film, “My Darling Clementine”, in 1946, starring Henry Fonda and Victor Mature. Another was “Tombstone”, starring Kurt Russell and Kevin Costner in 1993.

We love everything about London, and visit often. There’s so much do there, Shakespeare at the Globe, Changing of the Guard at Buckingham Palace, Trafalgar Square, Piccadilly Circus, Houses of Parliament, Tower of London, Westminster Abbey and many, many other historic and fun sites.

With all of those wonderful things to experience in such a big city, getting around London can be a challenge for visitors. Let’s examine the best ways.

Walk: Do some homework before you get to London. When you check in to your hotel, ask for a city map and a briefing of sites you plan to visit.
