Hey Stephanie,
It's Izzie with @Marlon-and-Izzie0.
That's great news! Provided they are telling the truth, and you can never really determine that - with any guest, you still have control.
I had a guest that originally booked for several days, and even requested a discount. I was happy to comply and then she requested a date change, which was fine. Unfortunately, she decided to cancel, I exercise the Strict Policy, so she ended up losing 50% of the original reservation total fees. I sent her a message, which is a template in my "Saved Messages," and offered her a small discount for a future booking should she decide to consider booking with us again in the future. Grant it, this is very unlikely, HOWEVER, we technically didn't loose money on a cancelled booking (we maybe even gained a little profit for no booking at all) but we also saved potential future business via her word of mouth. Although not all cancelled guests who loose money will see it the same way, I like to think of the later.
So, in your situation, this is what I would do:
If you haven't already, decline their request, but first send them an message notifying them that you are doing so. The reason you are doing this is because you would like to provide them an alternative offer. Explain to them what you explained in your last post. Let them know that if they wish to shorten their stay, they will not get the same discount as was originally offered. If they are reasonable, they will understand.
If you like, you can include that, if they are unhappy with your offer, you will work with them to find a resolution that will still benefit both guest and host. Also remind them that if they decide to cancel all togehter, that they will not receive a full refund, however, you will offer to assist them find another Airbnb host in your area that maybe more accommadting and within their budget.
Often times, guests won't hold you to that offer, but this shows them that, although you are not backing down on your cancellation policy, or original price, you are willing to work with them.
I have some templates you are free to use if you like, adjust them to fit your needs. Message me if you would like them.
Hope this is helpful!
Happy Hosting!
