Discover Los Angeles' multicultural history by walking through its diverse selection of neighborhoods: See the ornate Twin Towers Dragon Gateway in Chinatown and the traditional Mexican shopping stalls and vendors of Olvera Street. Then, chill by the beach at Santa Monica Pier, or take the iconic drive down Sunset Boulevard, one of the most often-filmed thoroughfares in the country. Santa Monica, Venice, Malibu and Long Beach are four of Los Angeles' most popular beach destinations. Of the four, Malibu is the most remote and least urban — head here for surfing and stand-up paddleboarding. Depending on traffic, you can get to Long Beach in 40 minutes, while the others take around an hour. Snap a pic of the Hollywood sign, stroll down the Sunset Strip and the Hollywood Walk of Fame, or visit Paramount Studios. You can see all of these and more on the Grand City Tour by StarLine Tours which operates two times a day, seven days a week.

The International Date Line is the meridian that separates two consecutive calendar days. Of course, since the line is mainly across open ocean, you can't see it. But without the IDL, if you cruised west around the planet you'd discover that when you returned home, it would seem as though an extra day had passed. This situation actually happened to Magellan's crew when they returned home after their circumnavigation of the earth. If your cruise should take you across this imaginary line, our staff will let you know the exact time one day turns into another - just in case you want to celebrate.
