+> Hi Cheyenne,
+>
+> We're staying at the cabin Sep 24–27 (booking 6373971385). Back in June
+> I extended the stay by a night, but our plans have changed and we now
+> have to leave for LA on Saturday the 26th.
+>
+> Would you be able to shorten the booking to Sep 24–26 and refund the
+> added night? I'm asking now rather than later so you still have ten
+> days to re-book the Saturday. I've also submitted the date-change
+> request on Booking.com so it's easy to process on your side.
+>
+> Let me know what works. Thanks!
