Born in Puerto Limon, Costa Rica, to Chinese parents, Harry Shum Jr. was once best known for his dancing in films such as “You Got Served,” “Stomp the Yard” and the “Step Up” films. But, today, “gleeks” worldwide know him as dreamy high school student Mike Chang on Fox TV’s hit show “Glee.”

Best known for his role as coroner Dr. Albert Robbins on CBS’ “CSI: Crime Scene Investigation,” actor Robert David Hall is also a musician. Hall’s current CD, “Things They Don’t Teach You in School,” showcases his bluegrass and rockabilly sensibilities. Hall — who had to have both his legs amputated after a car accident — has a wicked sense of humor and delights in the fact that Dr. Robbins was designated as being one of the Top 5 Cool Nerds on television.

Marissa Jaret Winokur won a Tony Award for her role in the Broadway musical “Hairspray,” competed on “Dancing with the Stars” and currently is a co-host on the CBS day-time chat show “The Talk.” “Life is good,” says the 36-year-old actress who beat cervical cancer a few years ago. “I am so busy working and being a mom that it’s all I can do to get a shower in every now and again. But I’ll take it. The good, bad — everything.”

Singer, actress and former “American Idol” runner-up Katharine McPhee, 26, was born and raised in Los Angeles, where she currently resides. “I love traveling and am on the road all the time for work, but I don’t get to go on as many vacations as people would think,” she says. “But a lot of people can work on vacation or relax while they’re traveling for business. And that’s what I’ve started to do.” Her favorite vacation memory, actually, is of the days off she had during a business trip to Italy. McPhee’s latest CD is “Christmas is the Time …(To Say I Love You).”

Guitar legend Joe Satriani and his wife, Rubina, are big fans of traveling, whether it’s a quick flight to Vancouver or an exotic vacation on Tioman Island. Though he enjoys the peace and tranquility of villas that offer little distraction by way of phones and televisions, he also admits he’s partial to having access to the Internet, especially when he’s on tour.

You’d think Keith Johnson — who spent his early years traveling around Europe with his art dealer father — would want to spend all his free time exploring boutiques and museums. “No,” says the 53-year-old star of “Man Shops Globe.” “I surprisingly am not a big shopper or museumgoer. New York fills my need for constant visual stimulation. I love the variety of sights and sounds. It also reminds me how big the world is and how I need to get out and see it.”

HGTV designer Monica Pedersen can be seen regularly on programs such as “Bang for Your Buck,” where she shows homeowners how to maximize their living space and beautify their homes. A well-seasoned traveler, Pedersen — who resides in the Midwest — sees the potential in taking trips to Wisconsin, as well as heading overseas for a longer family vacation.

His high-pitched voice and shaggy bangs are as much his trademarks as his dry, sardonic wit. And Emo Philips, 53, a comedian for most of his adult life, can’t imagine doing anything else. “It’s just something that works for me,” says Philips, who resides in Los Angeles. “I get to travel and tell my stories on stage. It’s the ideal life for me.” Though he executive produced the original 1992 version of “Meet the Parents” (the film that didn’t star Robert DeNiro) and dipped his toes into film and television work, Philips isn’t looking to make a mark for himself as an actor.

“I’m a good stand-up comedian and can’t say the same about my acting abilities,” he says. Philips talks about his travels, including a trip to Nepal where he got to witness — among other things — a cremation ceremony.

“Traveling is a wonderful perk of my job,” says singer Al Jarreau. “I wouldn’t trade it for the world.” A recent tour took him to Seoul, Beijing, Shanghai, Manila, Bangkok, Hong Kong and Jakarta, but not Tokyo — one of his all-time favorite cities. The seven-time Grammy Award winner in jazz, pop and R&B is best known for his smooth hit singles “Never Givin’ Up,” “Moonlighting” and “After All” and his greatest hits album “Al Jarreau — The Very Best Of: An Excellent Adventure” will be in stores on Sept. 29.

Born in Melbourne, Australia, chef Curtis Stone, 33, has lived in Los Angeles for the past three years but says he’s a traveler at heart. The star of TLC’s “Take Home Chef,” Stone has a new book in stores called Relaxed Cooking with Curtis Stone: Recipes to Put You in My Favorite Mood (Clarkson Potter). Stone, 33, talks to us about his travels and why America offers so much for visitors to see.
