After cutting the bracelet at 12: 00 do i still get food and drinks?

If you arrived late on your first day and did not get your lunch you can have it on your last day and drinks as well in the main restaurant.

what is the time of check out? and what shall i do if my flight is on a late time?

Check out time is at 12:00 and if you need to keep the room it will be against 25$ Till 18:00 or you can leave your luggage at the luggage room at the reception and use spa for showering and clothes changing.
