It seems you're always pumping Koala for some reason (not sure if you have a vested interest in them) but you may already know that Koala gets most of their guests from re-listing your rental through them on Airbnb (just marked up). Basically playing middleman between an owner and Airbnb guests. Nothing against Koala as they are another good alternative to renting out timeshares and it's great to have diversity and competition (e.g Redweek, Airbnb, TUG, VRBO). It's great for those who don't want to hassle setting up an Airbnb listing and managing an Airbnb account as Koala makes it easy to list on their site, but let's not kid ourselves that the eyeballs they get for their website is probably less than 1% of Airbnb.
