I would expect Fear Factor Live to be open for Thanksgiving since that's one of the most crowded weeks of the year - it'll just be coming out the theater's conversion to Bill & Ted's Excellent Halloween Adventure for the Halloween Horror Nights event, which is really the main reason it's "seasonal" at this point (I think it also doesn't run for a few weeks in January, or something minor like that.)
As for refurbs... Jurassic Park River Adventure just came out of one, so that'll be safe. I don't think Dudley or Popeye typically go down until January/February, so those should be safe, too. Nothing really comes to mind, so unless it's something minor all of the major attractions should be good to go...
