I don’t have access the WSJ article, but here is a summary from The Points Guy, which you can read: https://thepointsguy.com/news/marriott-homes-and-villas-vacation-rentals-launch/
The thing that is interesting to me is that this is not a direct competition to Airbnb, just by scale alone. Here is an excerpts from the article: “With about 2,000 properties available to rent, Marriott certainly won’t be edging out Airbnb which, by comparison, has approximately 6 million homes listed by its own estimation. Its homes won’t be exclusive, either, so you might find the same home listed by both Marriott and Airbnb. The key difference will be the ability to earn points, which Marriott is expecting to be a major incentive. “
It is interesting to see this announcement, given Airbnb’s expansion into the Hotel Segment with their recent acquisition of Hotel Tonight.
