Then, you will rollover to 2013 any nights in excess of the level you have achieved in 2012! Lets say you have 80 nights in 2012, you will get Plat for 2013 and rollover 5 nights. If you have 60, you ll be Gold and rollover 10 nights. The 18 nights of the challenge count as regular nights for rollover purposes!!
