I agree with the previous posts here about housing features; if a poet is touring far from home, they almost certainly are not being paid enough to get a hotel. I've certainly found myself stuck far from home with no place to stay after a show and only $50 (minus dinner and tips) in my pocket. It kind of sucks.
As a SlamMaster, when I book a feature, I ask them if they will be looking for a place to stay, and warn them that unless they are unbearably cute and/or at least one audience member is thoroughly drunk, it might be difficult to get a bed on short notice. I try to house every touring poet who asks (bed, couch, or floor, depending on how many I have crashing that week), but I understand that not everyone has the luxury of the room to do so.
I don't have a lot of pity for poets who tell me they are all set a month or a week before, then call me morning of panicked because they didn't set up housing, despite having had plenty of time to plan.
Similarly, I think it's totally inappropriate for the poet to cancel on the day of the feature. If, for whatever reason, there's no place to stay and they know that's a necessity, they should cancel then. Any last-minute cancellation puts the host in a tough spot.
