I don't think so. The VRBO market has existed for years (decades even) AirBnB just made it marketable and easy to enter. The controversy with them is some of the property owners are really taking the piss and treating their residential property as hotels and not paying the hotel taxes (BTW, Florida is 20%).
All the reports I've read have been spot on (though the AirBnB founders disagree). The hotels are paying this tax. Some of your members properties look awfully like a hotel. You collect the money, you collect the tax.
Unlike the taxi companies who actually have a monopoly, the hoteliers just want the same deal to apply to everyone.
