I just cross populate the calendars on both sides and it works absolutely fine. I have multiple properties. I have a Facebook page but no website. And they stay booked
@Matt3923 all platforms support ics calendar import/export at no charge. Google “Airbnb help sync calendars” and “vrbo help sync calendars”. If you’re looking for website and channel management software there are many options out there. I use MyVR because it can push Wheelhouse pricing to Vrbo.
