RentalBell offers a free availability calendar for websites, known as the Accommodation Calendar, which automatically syncs with various platforms and allows users to view and book accommodations directly on the website. This solution is designed to help property managers and owners of vacation rentals, hotels, and other accommodations manage their availability and bookings more efficiently. By using the Accommodation Calendar, these businesses can reduce the risk of losing customers to competitors and provide a better user experience for their customers.
