Not sure anyone could answer this, but my wife's challenge concludes January 31. She has a 5 night stay for work where the last night is the night of 1/31 (so completing the stay the morning of 2/1) that will put her up to 17 nights for the challenge. She refuses to do mattress runs, so no option to split up stays. Anyone know if that will count as occurring by 1/31 or not?
