I heard from a local host that they were letting guests leave bags after others had checked in, and thought that was a good idea, friendly and all that. I noted that if anything were to go missing from either guests things, they’d be held responsible. Not a good plan.
I've had plenty of requests for early checkin (to “just leave the bags”) that usually result in the guests showing up early and expecting to stay- wanting toilet and shower and even trying to take naps while the cleaners are still there. That obviously doesn’t work (and in many situations, running the housekeepers out because it looked finished on the surface, but wasn’t done- dishes and laundry etc still running and sweeping/mopping still undone... then complaints because they later discovered, wow, it wasn’t done!?!). Now I just say no. In a polite and professional way, that the cleaners will be there and prefer to focus on the task “so they can be done quickly to allow the earliest possible checkin time”. Usually that works, and guests like that answer. If we are able to get them in an hour or two earlier, they review us super well for bending over backwards to accommodate them. Win-win. And no bags left.
