A frequent traveler, lately I’m beginning to have problems with sight, balance and other skills I once took for granted. How do I get started on assistance for future flights? Mrs. MJL, Memphis TN

A: Enlist a younger friend or family member to fly with you. And/or take along a trained helper dog. There are basically three types: service, emotional support and therapy. Before making a decision, check with your family physician to determine which type of trained and certified dog, as required by airlines, will be best for you. For more info, go to usdogregistry.org

My widowed mother recently retired after a lifetime of world travel. She was recently diagnosed with early stages of Alzheimer’s, but is otherwise physically OK. We’re planning a Caribbean cruise, and she has asked to go along. Ideas? BRL, Boston MA

A: First, check with mom’s doctor and ask that question. If OK, be sure she will be with another person, day and night, throughout the trip, and takes required meds correctly. When boarding flights and the cruise ship, let employees know about her condition, and ask for help when needed. For advice before you go, consult the Alzheimer’s Association 24-hour helpline at 800-272-3900.

Now retired and in my late 60s, I’ve become a world traveler and selfie freak. I’ve snapped photos and videos of me at the Eiffel Tower, Great Wall of China, Golden Gate Bridge and other famous spots. We’re heading to Vegas next month for the first time in many years. Where are the best spots there to continue my selfie photo obsession? JL, McLean TX

A: Get a lot of great selfies while wandering at night. Our choices are Fremont Street Experience, fountains at Bellagio, Eiffel Tower at Paris Resort, and do a selfie smile and a wave by the famed Las Vegas sign. For overhead scenes, invest in a ‘copter flight or ride the High Roller ferris wheel at the Linq

Q: We’re retirees from a town with few crimes. We'll attend the marriage of a favorite niece, and hear all the stories about San Francisco street violence and homeless camps. Some happen near the hotel where we’ll stay for three nights. We want to sightsee the city, but at advanced age and physical limits, is it too dangerous for us? PLM, Ft. Collins CO

A: See the famous sights in San Francisco, but do it safely. Ask a younger adult wedding attendee or couple to join you in a tour. Or if that isn’t possible, ask the hotel desk staff to recommend booking a local company that conducts guided tours around the city.
