I can't speak to Ms. Rubin's thoughts, but I can share one of my own in regards to attendees needing to pool resources to attend. We offer a rental that comfortably sleeps 8 at a rate of $200/night. Last year we hosted attendees who brought 10 people and shared that cost. This year, the same group wanted to bring in 15 and expected them to share the space and the cost. They absolutely do, in some cases, have to pool their money in order to attend. The group we hosted did appear to be clean; however, I have heard from other landlords about groups that most obviously were not and the messes they leave.
