That party just sold out on 9/18, so if you call the ticket line ASAP, you just might be able to buy tickets. If not, it is possible that there may be some tickets available first thing the morning of 10/19 at the ticket booths, but that is a long shot. In the past, there have been a limited number of tickets available for guests at the on site hotels first thing at the hotel desk on the morning of each party. Or you could try booking the Mystical Spirits dinner package at the BB for the 19th. Some people have reported being able to purchase sold out party tickets along with the BB dinner package. There is no buying/selling of tickets here on the boards, so I hope one of these options will work for you.
