We’ve all seen movies about how passengers dined on luxury liners many years ago.  In “Titanic”, “Affair to Remember” and other examples, men appeared in tuxes and women wore long. elegant evening gowns.

Many cruises today still require passengers to dress for dinner, although not quite as strictly formal. Jackets for men and cocktail dresses for women.

Another requirement in those long-ago days was that passengers were assigned to one ship’s dining room table throughout the cruise. They had to be there with the same people at every dinner.

Did your most memorable cruise involve sailing for a week or more in less-than-luxurious quarters in the ship’s four-bunk-high troop compartment? Was the exciting destination Normandy, Iwo Jima, Inchon, Danang or Baghdad?

If you yearn to cruise again, this time in more peaceful waters, you can do it at attractive prices. Most major cruise lines offer generous discounts, averaging from 10 to 30 percent, to active U.S. military and veterans.

The offers vary in amount, destinations and other factors, and in order to get the best deal, you need to do some internet surfing and/or phone contact with cruise lines and travel agencies. There are also online agencies that specialize in military discounts for cruises and other travel programs.

Millions visit Sin City every year, and once there, never wander far from Las Vegas Boulevard’s resorts and casinos. However, there are many great sites within easy distance that can make quite an adventure beyond gambling.

Consider experiencing replicas of many areas of the world, all within walking or taxi distance right on the Strip. And they make great backgrounds for selfies. If you’re in a Caribbean mood, go to the Mandalay Bay Resort, with sandy beach next to surfboard waves in its enormous man-made lake. If you want a taste of France, visit Paris Resort, where you’ll wander and wonder at almost-life-sized replicas of the Eiffel Tower and the Arch of Triumph.

Senior Visiting Editor PJL, Tampa FL: For the first time in decades as a healthy frequent flyer, this year I’ve had to travel as a disabled person. After nearly 70 years of excellent health, advanced arthritis now requires a cane and walker.

These days, as we prepare to visit faraway family and friends, my own experiences may help ease similar needs of other senior physically-challenged travelers.

1. Check with your physician to discuss upcoming travel plans. If your medical condition is not up to the expected difficulties, consider postponing or canceling the trip. Don’t attempt stressful activities that could worsen your health, as well as cause concern and inconvenience for those traveling with you.

2. Once approved, take an adequate supply of all meds you normally use daily, both prescription and over-the-counter. Take enough for all time you’ll be away from home, plus extra in case you’re delayed. Put all into a see-through pouch, so that airport inspectors can quickly examine them.

It’s also important to include your doctor’s signed prescription forms that cover those meds, as well as the doctor’s address and phone number. Keep a copy of the list of your daily meds on you at all times while traveling.
