The HomeAway 2019 Trend Report gives new insight into travelers’ vacation rental preferences.

Over the last year, the report shows demand for castle rentals are up 55 percent and estate rentals 25 percent. The overall most-desired vacation home feature? Swimming pools.

Generation Z travelers, ages 24 and under, prefer getting away with friends over traveling with family or solo.

“What is so striking about this year’s findings are the generational differences they reveal, and their implications for vacationing and vacation home rental activity for years to come,” said Melanie Fish, HomeAway. “For one, more than three quarters of these newly independently vacationing Gen Z’ers have already stayed in a vacation home, cabin or condo at some point in their lives, making them far likelier than their parents to consider vacation rentals a primary lodging option as they continue to mature.”

Among the fastest-growing vacation rental destinations, Hocking Hills, Ohio, southwest of Columbus, took the top spot. Other up-and-coming vacation rental destinations include Newton County, Arkansas, and Loudoun County, Virginia. However, the favorite vacation rental destination still remains Florida, with other popular spots including Gatlinburg, Tennessee, and Gulf Shores, Alabama. As far as international vacation rental destinations, Paris, London, Rome and Florence all ranked highly.
