I have a question related to this topic.

I need to get in one more stay this year -- I'm two away from having another free night, and I only have one stay scheduled before the holidays. Sadly, I live in a Hyatt Place-free part of the country, so my three local options are somewhat expensive. What I'd like to be able to do is find the cheapest night at any Hyatt property within a certain distance over a certain period of time. Say, the cheapest night at any Hyatt within 25 miles of my home prior to 31 December. Is there an easy way of doing this?
