I have a similar concern. We have a house in Upstate NY and there is no dumpster on site. Guests would need to take out the trash to the local transfer station (I believe 3-4 miles from the house.) Some guests haven't, although it was stated in our welcome book to do so.
I also do believe we can't expect guests to take out the trash off-site when we are collecting a cleaning fee already.
Wondering what the best solution is since the house is far from our actual home (3-4 hours away) and we can't go and do it ourselves. Also the only one neighbor there isn't budging to help.
