I have used vrbo to find great rentals for our vacations since 2004, and I have always been happy with where we stayed and the owners who rented to us. Apparently VRBO.com/Homeaway.com (bought out by Expedia) is now charging a "service fee" of 6-10% of the total cost when you book a rental property on their site.
The money goes directly to vrbo/homeaway-- the owner of the rental does not get a dime. Apparently, this fee "Helps VRBO provide a safer and more secure booking experience, coupled with premium 24/7 support throughout your trip."
Who calls VRBO if they need assistance in a vacation rental? I highly doubt that VRBO/Homeaway knows the wi-fi code, can call a plumber for a specific rental in case of emergency, or can take care of any other issue that the HOMEOWNER takes care of. VRBO/Homeaway seems like they intend to act as property managers, without doing anything to care for the property that they are now charging the owner to list and accept credit cards, and charging renters for the "opportunity" to rent through their site.
