I was goofing around with searches and found that JW Marriott Istanbul is 100 Euros for 5 nights or 161 Euros up to 4 nights. I am planning on staying for 4 nights, but it is cheaper for 5. Would they charge me 161 per night if i check out a day early?
i dont know Turkey, but how would they know that you left on day 4? Couldn't you just leave sometime on day 4 and check out on the app on day 5? Going to the desk, and formally checking out will result in a rate change almost certainly.
