The issue is... in my case, is that it takes me more than 24 hours to respond, so there should be some flexibility in that "rule" or being "dinged" for letting it expire!?!? My property is a resort, and I have to get approval from the membership department as to availability, and that sometimes takes a day or two. Plus, I state right in my description to NOT send inquiries, but rather just a "message" to owner/host/mamager, and then book from there. NOT EVERYONE fits in the same box, so flexibility is key in making this work for everyone!?!?
