While you're resting, your dailies aren't calculated.
Warning: this means that if you check in today, do some dailies, and check out tomorrow - they won't get un-checked until the day
after tomorrow. You start where you left off before vacation / illness, and it prevents abusing the inn. See
Trello for more information.
Whilst resting your dailies are saved and aren't effected by day turn-over. Whether you check out tomorrow or in a weeks time you'll continue in the same state as when you checked in.
