Query: Useful, but disappointing.

The basic premise of this book is great...simple ideas for preparing and marketing your vacation rental property. However, the author acts as an authority, yet trips on her own mistakes. For instance, her heavy suggestion that a VR owner hire a professional writer or editor is overshadowed by the fact that shehas numerour grammatical and punctual errors in that very section of the book! Overall, the meat of the book is a bit lean. She touches on many good points lightly. The author is now employed by a VRBO website: i.e., she's making her living not just as a vacation rental owner, but now working for a website which advertises the VRBOs. That to me underscores that she is willign to go where the money is, and may not necessarily be the expert she portrays herself to be. Some great ideas here, but not to be taken as the "bible" of the VRBO world by any means.
