Probably not. Unless it's summer, spring break, or Christmas break, it only shows Fri-Sun. I personally think it's a cash saving move and that they should run it every night of the year. To me, it's not a Disney Park unless there's a big finale' to finish the night.
My guess is also probably not. Historically, they've usually only presented F! on the weekends (Fri, Sat, and Sun) outside of the peak periods. They have presented it nightly the week of Thanksgiving in the past, but that's the week before you'll be there.
