Congratulations you got that mega job done! it sounded daunting a few monts ago, but didn't want to comment and dampen your enthusiasm 😉
My check-in is from 14h on - how difficult is that?!
Every time I used to ask what their ETA was, and around almost half then named a time before that in the morning.
(well, I did ask when they arrive, duuhh)
Then I started saying my check-in window is... and followed up by "approximately what time after 14:00 (2PM) do you expect to arrive at my place?". That works better, still doesn't filter out asking for earlier arrivel or baggage drop....
So now I ask with saying as above my check-in window is...but also add that I probably won't be home much earlier than that and "approximately what time after 14:00 (2PM) do you expect to arrive at my place?"
I always feel like I'm repeating way too many times, but a couple of recent visitors have again shown me that conversations in the past are often magically wiped from memory...
So now it'll additionally refer to the time they named at some point and say I'll be home in good time to receive them.
Although it's super irritating when it happens, it's always the little push to re-evaluate where the leaks may be in my manner of communicating and how to improve on not inadvertently giving too much option leeway.
In your situation I'd also stress before accepting or right after accepting a booking how important it is for check ins to be before a certain time. Then repeat it again later.
I'm floored by how much guests forget, really. And I've noticed how apps seem to only induce this more and more. Old-fashioned paper hard copies give much better oversight than fidley, jumpy little screens that only show a limited amount of signs at any one time.
Really, don't rely on pple remembering or even reading what's in your listing alone. A good third or more of my inquiries and requests miss the most important parts, so I've become this automated Momma Bear, but it sure has helped fine-tune things. And where it didn't go as well, was where I'd gotten lazy in reminding or broken my own rule.
Maybe there's something here that's adaptable to your situation, though it's obviously more difficult in an area not near an airport and which involves arriving after a drive of several hours.
