We are planning a trip for April 2008. First, does anyone know how soon we can book a room only reservation? Second, if we do book one, and a discount code comes up for that time period, can we apply it at that time? Lastly (this is long-winded, I know), can we ait and see if an Annual pass code comes up before buying an annual pass? If one does, can we get one, and then call and use that discount?
