Ignore or not. You said there is case law covering this. Post it. If you cannot post it then it is proof you are all talk. Apparently not even PCL can help you on this one.
Personally, I'm not aware of the case law. But I'm also not an attorney, I don't play one on TV, and I haven't stayed at a Holiday Inn Express in quite some time. So I would suggest that you talk to an attorney if you want to get information on case law.
