From Oregon Trail-style glamping to tequila barrel sleeping pods, the 2018 travel trends reveal the increasing demand for unique travel experiences and unorthodox accommodations.
In recent years, consumers have opted for more unconventional vacations over typical beach trips. As a result, hospitality companies have begun offering more innovative travel packages. For instance, the Bawah Island resort near southern Malaysia is a remote paradise that caters exclusively to luxury travelers as it is only accessible by private plane.
Similarly, the 2018 travel trends reveal that consumers want unorthodox accommodations to match their unique travel adventures. Just take the case of Yosemite Pines RV Resort and Family Lodging, which now offers an Oregon Trail-style glamping experience, where guests can stay in real Conestoga covered wagons. Another example is the The McFly Airbnb rental in Dallas, Texas, which is completely covered in 1980s memorabilia.
