Asking guests to take the trash out to the curb isn't likely to work a lot of the time for two reasons- some guests may just neglect to do it, and if trash pick-up day doesn't coincide with booking dates, you could have a guest having to take a full bin of the previous guests' garbage out to the curb, which doesn't sound like it would go over well.
If you have neighbors there, as opposed to the place being isolated, maybe you could offer a close-by neighbor a bit of compensation to just move your bins out to the curb on trash days? A responsible teenager, stay-at home parent or someone who works from home, or retired person might be happy to make an extra $5/week for a few minutes work. Then you could just ask your guests, with a reminder note over the inside kitchen garbage can, to please make sure that all inside garbage is dumped in the outside bin by the evening before designated garbage pick-up day.
