This new iCal Feed feature could save you time as you will only need to maintain availability in one location.
This feature only Exports availability information to other sites. We do not Import availability at this time.
Using the new iCal Feed tool in your AvailabilityOnline Administration Center, generate an iCal URL(s) for each room/unit you choose.
You would then paste that URL into the appropriate location in the 3rd party website. This allows the 3rd party site to sync the availability information from AvailabilityOnline into the calendar showing in your 3rd party site listing.
