The world's biggest hotel company will take reservations for 2,000 homes in 100 markets in the U.S., Europe and Latin America.

Prices will range from $200 per night for a one-bedroom apartment to $10,000 for a full Scottish castle.

Meantime, Airbnb is encroaching further into hotels, planning a 200-suite site in Rockefeller Plaza in Manhattan.

Marriott International is pushing more heavily into home sharing, confident that its combination of luxury properties and loyalty points can lure travelers away from rivals like Airbnb.

The world's biggest hotel company will soon start taking reservations through its website for 2,000 homes in 100 markets in the U.S., Europe and Latin America. It plans to expand its Homes and Villas program to other locations.

For its part, Airbnb is encroaching further into hotels. On Monday, the San Francisco-based company said it's working with a New York real estate developer to establish a hotel with 200 suites in Rockefeller Plaza in Manhattan. Airbnb, which plans to go public but hasn't made clear when, also acquired Hotel Tonight, a last-minute booking service, in March.

Marriott is targeting families and groups, and the homes skew toward luxury, with prices ranging from $200 per night for a one-bedroom apartment to $10,000 for a full Scottish castle. Nearly 40 of the markets are in places where Marriott doesn't currently have hotels, like Bar Harbor, Maine, and Bordeaux, France.

Marriott is a long way from matching home-sharing behemoths like Airbnb, which boasts 6 million listings worldwide, or Booking.com, which has listings in 220 countries. The homes in its program aren't even exclusive Marriott properties. Marriott is partnering with rental management companies to handle the maintenance and cleaning.

But Marriott believes it has advantages. Unlike its home-sharing rivals, it has a loyalty program that lets travelers earn and use points on its hotels and homes. Business travelers can accumulate points at Courtyard hotels, for example, and use them for a week at a beach house. Airbnb is working on a loyalty program of its own, but the rollout has been delayed.

Marriott said it also guarantees hotel-like standards that are often missing in home sharing, such as Wi-Fi, crisp white sheets, bath amenities, baby cribs and smoke alarms. Airbnb has tried to tackle that problem with user reviews and its Plus program, which highlights rentals that meet higher quality standards. But the sheer volume of properties makes it difficult to police them all.

"One of the challenges you see with home sharing is there's too much inventory without quality filters or brand assurances," said Stephanie Linnartz, Marriott's global chief commercial officer. "There's inconsistency across the brand experience."

Hotels have struggled to determine the right path into the home-sharing market. Hyatt invested in Oasis, a luxury home-sharing site, in 2017, but said the company was struggling to grow because of regulatory hurdles. The companies parted ways last year.

AccorHotels bought home-sharing site Onefinestay in 2016 but has struggled to make money on it. Choice Hotels, like Marriott, partnered with property management company RedAwning and gets a cut of every property booked.

For now, the home-sharing unit won't be material to Marriott's earnings, Linnartz said. Indeed, Marriott's stock price barely budged on the news Monday, rising just 0.1% to around $136.60 a share.

Marriott's move is an acknowledgment that home sharing — which has boomed in the last decade since Airbnb's founding — has fundamentally changed guests' expectations. People may be satisfied with a cookie-cutter hotel for a business trip or a soccer tournament, but sometimes they want something unique and memorable, Linnartz said.

Marriott began testing home sharing with 200 homes in London last year, and later expanded it to several other cities in Europe. The company found that most of its home-sharing guests were leisure travelers and they stayed an average of 5.1 nights, or double the length of a traditional hotel stay.

Marriott's research also showed that 30% of its customers had stayed in a shared home in the last year.

"When they were doing that, they weren't staying at an offering from us," Linnartz told the Associated Press. "This is a gap we want to close."
