Thanks to all for the responses. It sounds like the major issues is that it's a lack of being tech savvy to expense. I was in the onliine hotel reservation business early on and eventually sold out to a major industry supplier. Even small private hotels got in fairly rapidly. Maybe the right solution hasn't been developed yet.
It could be due to my past being in the business, but I would like to go to a site and see only the options of places available over a particular date range. Much like you do when booking a hotel. That way I could be armed with only available places in a suitable area with suitable facilities to call. Calling blindly seem so inefficient. Am I alone in this?
