USA Today and GOBankingRates named 20 travel destinations you can visit for less than $100 daily. Others listed include Singapore, Madrid, Lisbon, Prague, Cancun, and Bali was the cheapest at $24. Las Vegas was #19 on the cheapo list.

The beancounters obviously haven’t been to Sin City lately. And why didn’t they include the expenses of getting there plus additional in-town costs? Round trip U.S. flights range from a cheap $200 and much higher. Also, the famed Vegas buffets now average $35 for breakfast or lunch, and $50 for dinner. Some bait ads quote hotel room rates at $99.99 per night. Then, all add the infamous daily resort fee, usually another $20 and more.

Show tickets are at least another $25 plus booze, food and tips. Finally, of course, there are the greedy Vegas casino bosses. Unless you spend your entire visit at local museums and sightseeing, expect to lose a modest average of $100 day playing the tables and/or slots. Of course, it’s possible you’ll win, but the odds always heavily favor Vegas.

Waiting for your flight, you may see them nosing about on duty. They’re now performing their skills at Atlanta's Hartsfield-Jackson and Chicago's O’Hare, but soon may go to work at other airports. With their sensitive noses, the trained Beagles sniff out grains and meats in passenger luggage that could bring in serious diseases and insects.

The woman leader of the city recently called for tourists to cool it in the famous red-light district. She insists the gawkers make it "unpalatable" and "humiliating" for the so-called sex workers. Over 20 million visitors now come to Amsterdam annually, compared to just 10 million in 2000.

Of course, the ladies of the night pose in their brightly-lit shop windows to hustle up business, and in Amsterdam are as legal as any other. And if they are as attractive to gawking, selfie tourists as the Mona Lisa and Girl With The Pearl Earring, so be it.

Within the next few years, airport face scanning and tightened security will be the norm. A new program, called “biometric entry-exit system,” will work like a super-sophisticated police line-up. It will instantly compare your features with millions of other faces on electronic file, including criminals, terrorists, anarchists, mental cases and other dangerous people.

So, next time you’re in an airport, don’t be surprised if a Sherlock Holmes scan happens to you. Sometime, somewhere, someplace when you least expect it, something gets into your face and says, Smile! You're on Candid Camera!
