I have an AP, so with the discount, September 24 is $35 and FFP is $60. That's a $25 difference for me, plus last year I got a FFP and like an idiot I ended up going only once... so that's part of why I'm not sure if I should get the FFP over the single day ticket.
But this year it might be different for me. I'm leaning more towards the FFP, especially because I'm also planning to do UTH tour on the 25th, so I could just stay and go the night of the 25th as well. Then the FFP would pay for itself and I'd have the chance to go again, so FFP sounds very appealing...
I'm buying my tickets next week when I get paid, so I have until then to decide
