It's sad to say this is true. In many cases, it's just as cheap, if not cheaper, to use Starwood SPG.com or Priceline, plus you get free points or have points to use from a credit card. You also know that while it won't be as personalized an experience as AirBnB, you know that bedsheets will be clean, there is maid service, decent amenities (like a pool or workout room), and room service often at the same price for AirBnB. And you also earn points for your stay.
