Not for a year, or at least not in advance.
It is a prize being awarded 367 times through the end of next year. Now, the winner of the prize won't always be able to stay in the room so I suppose it is possible that the hotel will then let someone else in, but I don't know that to be fact.
It is definitely a legally governed prize in the contest (
here are the detailed rules as required by law and the penthouse is one of the prizes mentioned).
