Unfortunately, by default, the Rent/Book Now section only uses a simple contact form (Contact addon). For professional use, we strongly recommend integrating a more advanced solution, such as:

1. An additional installed component/module.
   Useful booking and reservation manager for Joomla, which you can find here: https://extensions.joomla.org/category/vertical-markets/booking-a-reservations/
   OR
2. Link to external online reservation system (available in many languages).
   An online booking system is a software you can use for reservation management. Booking systems are what’s called software as a service (SAAS). Everything is stored in the cloud, so you can manage your reservations on any device, anywhere you need to.
