Not for regular cost tickets.
However, as of last Thur when I went to buy Advanace PAP discount tickets the ones for Fri, Oct 7 were sold out. But only for the Discount AP/PAP tickets, which saved me about $10 each!
So we are going on Thur, Oct. 6, which was my first choice anyway.... as I thought a Thur night would be less crowed then a Fri night. Not that I think either will be crowded that early in the month. But it was nice to get what I wanted.
