I expect them to just show hotel tonight data in the airbnb interface. From the press release:
> We are making it easier for people who use Airbnb to find last-minute places to stay when Home hosts are often already booked. The availability of boutique hotels—in addition to private rooms and entire homes that are instantly bookable—helps ensure authentic, high-quality stays are available on-demand, especially at the last minute.
I think about it this way all the time: AirBnB bought the product for X price, because they think it will help them make Y more money. They don't even need to "merge" as long as the product is profitable but if they can get even 1% more with a cross over, then AirBnB (the parent co) is making even more money (with more risk ofc)
