King Neptune would be jealous if he saw you living lavishly in your underwater suite at The Muraka at Conrad Maldives Rangali Island. Of course, you’ll be perfectly dry behind glass as you watch seals, sharks, turtles and other free-roaming sea life swim around and above your private, waterproof aquarium.

Of course, such luxury will cost just a tiny bit more than a regular on-land luxury hotel suite. However, if you have a mere $5,000 per night to spend, this unique experience offers the precious underwater memory of a lifetime. By the way, the sweet suite price listing doesn’t include taxes and tips to your private butler, waiters, cleaning staff and other hotel employees.

Your travel4seniors.com editor served in World War 2 and Korea. Still a Navy Reservist in the mid-1970s, I received a call asking me to volunteer for  active duty for the Vietnam War. At age 40, I declined. Would I voluntarily go to Vietnam today as a tourist? Well, just maybe.

Would I enjoy the beautiful Hanoi city scenes, river cruises, exotic foods and other offerings? With the memories of John McCain and other POWs enjoying the luxuries of the Hanoi Hilton, some serious thoughts occur about America’s former enemy. Of course, after WW2 it didn’t take long for American travel to Italy and Germany to become fashionable. Why not Vietnam today?

So, if interested, check with sources such as Intrepid Travel on currently peaceful Vietnam visits. Enjoy a meal at a Buddhist nunnery, take an overnight boat trip on Halong Bay, and zoom on a motorbike tour through Hue on the Vietnam Express.

It all begins in Hanoi and ends in Ho Chi Minh City (formerly Saigon). This 10-day trip is designed for single travelers. You’ll be with a roommate of the same sex unless you prefer a room by yourself at an extra fee. The tour, priced from $1,100 is available on select dates through November 2019. www.intrepidtravel.com/us/vietnam

One of the most popular museums in the world, the Louvre attracts more than ten million visitors every year, and charges an entry fee of about $15. However, next time you’re in the French capital, instead of being crammed in with other gapers in front of the Mona Lisa during regular visit hours, do it privately.

If you have the dough, it will cost a mere $34,000 for up to four people in your exclusively wealthy group. You’ll be escorted through the museum in the evening by experts for about two hours. Hmmm, so when the tour is over, do you tip the guides ten percent of your enormous entry fee? If you’re considering the tour and other Paris attractions, get more info at family-twist.com.
