It’s the oldest sales trick in the book: Tell customers demand is high and supply low, and if they don’t act quickly, an offer will disappear. The nonprofit advocacy group Delaware Valley Consumers’ Checkbook found that many hotel-booking websites take this tactic to extremes. In a recent investigation, it found that when travelers shop for rooms on many travel-booking websites, search results repeatedly issue false warnings about scarcity.

For example, as you scroll through listed properties at Agoda.com, details about amenities and rooms for some hotels quickly disappear, replaced by “JUST MISSED IT!” and “Sold out on your dates! Our last room here is already booked. Check out these similar properties before they’re also sold out.”

Among hotels that still have rooms available, almost all get a bright red “Popular!” icon or bold warning of low inventory (“ONLY 1 LEFT!”). And if you’re not in panic mode yet, at the bottom of the page a banner pleads: “Rooms in [area you’ve searched] are in high demand. Book yours now!” Booking.com, Agoda’s parent site, makes similar breathless calls to book right away before you miss out.

The search results at Hotels.com (owned by Expedia) paint a similarly dire picture for most destinations: Many hotels are marked as “Sold Out,” and as you scroll down, popups detail the number of people looking at rooms you’re considering. As on Booking.com, many properties get a prominent red alert — “Only X left” at the price shown.

Checkbook’s researchers spent weeks searching various hotel booking websites. They encountered such high-pressure sales tactics at Agoda, Booking.com, Expedia, Hotels.com, Hotwire, Orbitz, Priceline, and Travelocity. The design of each website kept indicating that unless the shoppers quit their pesky shopping and booked right away, they would miss out.

Checkbook’s investigation found most dire warnings about low availability were dishonest: There’s usually plenty of room left at the inns. Checkbook conducted 80 searches for hotel stays in major cities across these eight websites; all spit out misleading messages. Checkbook repeated these searches three times over three weeks. Each time, shoppers got alerts about shortages that typically didn’t exist.

When Checkbook’s shoppers searched Agoda for a stay in Las Vegas, it added “ONLY 1 LEFT” next to the Homewood Suites by Hilton listing. But shoppers found that referred to only one room type — a “1 King Accessible Roll In Shower Studio Non-Smoking.” There were also three other room types available at that price, and Checkbook counted at least 19 rooms available for the same rate. The site still proclaimed, “Limited availability” and “This is a popular choice!” next to every option.

One of Checkbook’s searches on Priceline was for a spot in downtown Minneapolis. Shoppers received incredibly bad news: For 23 of the first 25 properties shown, the site claimed only one room remained. But when shoppers clicked to book these seemingly near-capacity hotels, they found many rooms available. At the Radisson RED, for instance, dozens of rooms were still up for rent.

So, what gives?

Often, when these websites warn that only one room is left, they’re referring to a cherry-picked room type with low availability. For example, Expedia told Checkbook “We have 1 left at $89 per night” for the La Quinta Inn & Suites in downtown Dallas. But after clicking on the listing, shoppers discovered Expedia’s warning applied only to a handicapped-accessible room with a king bed; otherwise, shoppers could select rooms in three other room categories, all available for the same $89 per night.

But Checkbook also often found booking sites don’t even bother to point to obscure room types to falsely advertise low availability. When shoppers searched for one stay on Orbitz, a listing for the L.A. Grand Hotel Downtown claimed only three rooms were left at $211 per night. But a click on the listing yielded two near-identical room choices for that price, and for these other booking options Orbitz reported nine rooms were available at $211 per night. So, combined, Orbitz listed 12 available rooms for $211, and if shoppers were willing to pay $212 per night, there were even more choices.

Even at hotels where Checkbook found actual low remaining room counts, the “shortages” lasted for weeks. After conducting those 80 sample searches, Checkbook’s shoppers repeated them a week later, and again two weeks after that. Despite sites cautioning to “Hurry!” or “Book now!” Checkbook found neither availability nor prices suffered with time. In fact, after collecting more than 3,500 hotel rates last year for a report on how to score the best hotel deals, Checkbook can assure there’s no rush: In most scenarios, hotel-room prices actually decreased the longer Checkbook shoppers waited to book.

Among sites Checkbook tested, Priceline had the most claims of room shortages. For the 10 searches Checkbook’s shoppers conducted using it, on average 21 of its first 25 listings had warnings about low availability. Orbitz was the next-worst, with more than half of its listings giving warnings about shortages. And the six other websites also advertised shortages that typically don’t really exist.

Checkbook concluded that these websites are employing misleading and dishonest sales tactics. Don’t let hyped-up language stop you from finding the best room at the best price.
