After a terrible experience with VRBO, Homeaway and a host of other websites owned by Expedia, which has become an industry consolidated, I decided to exercise the great American prerogative and try the competition. I decided to try TripAdvisor where I had an equally bad experience and guess what, all these entities are controlled by Barry Diller so I wasn't going to the competition after all. There are only two companies (a duopoly) which now dominate the vacation home rental business. One is Expedia and the other is Airbnb. Of two bad choices Airbnb is the better choice. Since the vacation home rental websites like Expedia are now able to price gouge a vacation home owners rental Co-op would probably be the best solution to what is now a very uncompetitive online marketplace. Managing a Co-op can still be a very lucrative career for an entrepreneur looking for a great niche.
