There are plenty of hotels which are "adults only" for any number of reasons and I have not heard a complaint that these are discrimination.

Even under the US ADA, only hotels built after 1993 are required to provide compliant facilities. That means there are actual 100% for-profit hotels which are out of compliance. Perhaps frustration is more appropriately directed at them, or the provisions of the ADA than an individual trying to share his personal residence in a practical manner?
