VRBO is a service that manages to make sure they have ZERO responsibility to make sure your vacation is completed. They specifically are loyal to the people who rent to you and not to you. So then what happened to us is no surprise. We booked a home in North Carolinas for Christmas Holiday. We paid UP FRONT over $3,500 plus VRBO fee and insurance for an additional $500. Our family started preparations for this holiday until we received two credits on our credit card for a refund of the rent. When I called VRBO, they said "call the owner". The owner gave us a excuse that some software had double booked and very nicely said too bad.
So now VRBO has washed their hands of the matter and has still not refunded our Fee. Bottom line is VRBO does not care if you have a problem, they say contact the owner.
So be aware to contact the owners up front and get commitments or your vacation will be cancelled with NO NOTICE.
