Hours of set up
I'm getting ready to put in hours of time to set up syncing between our rental property booking website, Airbnb, and VRBO. There's a whole process to go through in order to make syncing possible as well as take bookings and credit cards through our personal website, but I believe it will be worth it.
The company we're using for the integration is Lodgify and they seem to be a growing force in giving rental property owners a way to get bookings through their own website. I'm looking forward to seeing how it goes.
