Senior travelers often are confused about tipping. In a few countries, it’s forbidden and factored in with the price of the meal or drink. In almost all other parts of the world, the diner and drinker are expected to leave a tip after satisfactory service.

So, how much should you tip? It depends on service, total amount and other factors. The most general answer if from 15 to 20 percent of the bill. Your travel4seniors.com editor remembers car hopping at a Hot Shoppe in Philly way back as a college student. With all our running around the parking lot, we were lucky to get 10 percent. And not so lucky when the no-tip car drivers tossed their empty plates and trays at us as they raced away.

Food servers, both indoor and outdoor, work hard and deserve a tip. Sometimes a generous one can be a happy surprise. Recently, some very generous diners have been leaving 100 percent tips through the #TipTheBillChallenge, and bragging about it on social media. Hey, where were you back when I was slaving at the Hot Shoppe?

OK, I’d take it for a week, but I’m a senior on very limited Social Security. Can I get it for $49,999.99 a night? The modern marvel is just off shore at the Conrad Maldives Rangali Island resort. And way down 16.5 feet into the Indian Ocean.

Of course, the super sea bottom suite comes with luxury features. Its glass walls allow guests to trade gawks with sharks, turtles, squid and every other creature that comes by for an external visit. The bargain price also includes full-time serving staff, special wining and dining, private boat, as well as many other luxury privileges. For more info, go to www.conradmaldives.com

How many flying seniors remember 30 or so years back when movies were projected on small screens up front of the passenger cabin? You could hear the sound track on the earphones plugged into your seat, but could only squint at the teeny images way, way up there. Not much different than little screens on 1950s television sets.

Now, as with some competing airlines, SW has ended the $5 charge for watching in-flight movies on seat back screens. The programs can always be prerecorded at home and seen on personal devices, such as smartphones. Also, SW passengers can now watch live TV broadcasts and some first-time entertainment videos on seat back screens.

Seniors are among the most avid cruise passengers. We enjoy the luxury of moonlit nights at sea, fine dining, colorful port visits and other amenities of sailing. However, we’ve all read history books about the disaster of 1912 when the original Titanic sank, and seeing scary movies that portrayed the tragedy.

We’re hearing about the Titanic II now under construction in Jiangsu, China, and scheduled to sail 110 years after the original ship sank. Not many of us consider ourselves as lucky as the Unsinkable Molly Brown, so we can just wonder how successful the new Blue Line cruise company will be in signing up passengers.
