Conversation...whether by phone, in person, via social media...is always most effective when done directly. 3rd party connectors like linkedin are FABULOUS because after the connection is made, we are in control.
What I am challenging you to think about is how 3rd party connectors (airbnb, expedia/homeaway/vrbo) are now trying to CONTROL the conversation to the detriment of guests and owners alike.
I have been booking my vacation home directly since 2004 and up until a few years ago was pleased with my 3rd party connector, VRBO. I paid them an annual subscription fee for all of my 4 listings and then the ball was in my court.
Unfortunately that is no longer the case. I am no longer able to connect with potential guests directly by phone before they give me their hard earned money, I don't receive my money until after check in, I am charged more fees in addition to my subscription and even worse, my guests are charged 8-15% to receive the same experience that they would get when dealing with me directly. I am encouraging you to join the movement to hashtag#bookdirect. Whether a private home or a hotel, always deal with the source and save money!
