Booking.com

Booking.com is the world's largest accommodation OTA, and its vacation rental inventory now rivals its hotel core. For hosts, it brings two things the US-native platforms cannot match: overwhelming international guest demand, especially European travelers, and hotel-conditioned booking behavior, including a strong instant-book culture. The tradeoffs are real: default payment handling, damage deposit mechanics, and cancellation policies feel hotel-shaped, and its commission plus optional visibility boosters run rich. But for markets with international visitation, skipping Booking.com means skipping a demand pool competitors gladly absorb.
