Paying a flat rate is not an abuse of human rights in any sense.No, most people are allowed to leave in less that 24 hours , some after only 15 hours. If they want to keep this thing they have to make it fair, that is refund all the money for unused portion of hotel stay. If your tests results are ready after 15 hours , you should be charged only for that time and it shouldn't cost you more than 200 bucks in that case... including a couple of meals. Otherwise it is abuse of people and violation of human rights.
