You will l see multi unit availability calendar somehow embedded into facebook (group or page). I know currently one cannot create tabs in groups.. maybe pages. I know several smokies owners use OR. Where I m going with this, maybe someone OR-participation properties could have "communal" availability calendar like this... Not even with price, but link and number of bedrooms would work!
Just a thought
I know this guy. He's in my building at Snowshoe. He uses Lodgix for his condo rentals
