I understand that this is a circular argument, but folks not staying on site is part of the issue with this or any venue that might host a pipe show. They're counting a high percentage of attendees staying, eating, and drinking at the facility.
It does not excuse bad housekeeping or management, of course, or require you to put up with the same. But as a group that requires special accomodations (smoking tent/circumvention of law) we are more attractive to this and future venues if we can reasonably promise to fill the host's hotel, restaurant, and bar for a long weekend vs just stinking up their ballroom and parking lot.
