Opinion: The most exciting destination in the world dedicated to gambling is Las Vegas. Consider your travel4seniors.com editor an expert, because over the past retirement decade, quite a bit of his money has been invested there.

Of course, return on the investment has been zero, maybe a bit minus zero, but the experiences have always been worth the cost. Seriously, Las Vegas has all you want just within walking distance on the famous Strip. Except when the temperature is over 110, which only happens at noon daily between April and November. Vegas boasts world-class entertainment, every kind of international food, luxurious hotels, fantastic pools and great shops. You'll enjoy all the elements of Sin City along with thousands of other seniors, including those in walkers and go-carts. And don't be surprised if you see an Elvis clone pumping gas, waiting on tables or at the bathroom stall next to you. Or performing marriages in the little wedding chapels along the Strip.

Another city that is exciting for many other attributes, including gambling is London. It has some very posh clubs where you can lose your money at tables alongside the very snootiest of British society. The city itself is full of fascinating historic sites, monuments and lousy restaurants.

Other great gambling destinations include Monte Carlo, Baden-Baden, Atlantis, Macau, Sun City in South Africa, Hong Kong, Singapore, Reno, Atlantic City and Laughlin.

To experience the world's very first casino, visit Baden-Baden in Germany. It was opened by some guy named Wilhelm the First, Frederick the Great or Hans Schickelgruber in 1809. It’s said Napoleon gambled there, and the reason he always held his hand inside his coat was because the casino took all his underwear, along with the French treasury. Loser Nappy probably stormed out griping, "Baden, Baden is real bad!".

Of course, because of all the James Bond movies, and when the Prince married movie star Grace Kelly, many senior gamblers were convinced that the Casino de Monte Carlo in Monaco was the coolest, hippest gambling joint in the world. Today the city is slightly threadbare, the casino building actually a creaky old palace more roomy and rheumy than Buckingham.

When your travel4seniors.com editor was there several years ago, he was told the grave of Princess Grace Kelly, was just down the street from the casino. No grand statue; she's under a simple stone slab on the floor of a little lonely chapel.

Some senior travelers are not charmed by the Caribbean. Mostly cookie-cutter Club Meds along with poverty and angry residents. However, the Atlantis Resort Hotel in the Bahamas is the largest and most luxurious casino in the Caribbean.

The hotel is a beautiful structure, featuring twin towers connected by a scenic, sky-high penthouse walkway. Luxury suites in the penthouse cost $25,000 a night, so at least some people on the island are not poverty-stricken.

Although your travel4seniors.com editor has been all over the world, and has sampled many gambling areas, it’s always back to Vegas. In fact, within the past several decades, Vegas has gone intercontinental. For the flavor of France, there's the posh Paris Resort.

For Italy, there's Bellagio and the Venetian. For ancient Egypt, there's Luxor. And if you want a taste of the Caribbean without all the flight time and poverty, there's the Mandalay Bay Resort.
