Direct Book- Customizable Reservation Requirements
Currently, the only required information the guest needs to input when instantly booking via Hostfully is their name, email and dates. We need to collect mobile phone numbers, whether or not they're bringing a pet and would like to require a message from them about their stay.
For instant booking on Airbnb, you can require the guest to answer your customized questions at booking. It would remove so much back and forth for me if I could customize what we capture from the guest at the time of booking.

Regarding customizing the booking flow for pets, the system provides a very elegant and customizable solution, which is described in this article: https://help.hostfully.com/en/articles/6895588-handling-pet-fee-in-the-hostfully-booking-flow

Thanks for your idea, Chelsea! We've received it and will consider this improvement next time we work on the Direct Booking Site.
