Open like normal. Most of the specialty dinners are held in the old Odyssey restaurant, that is only open for special events. But they can always change things, add more, etc.... But for the most part, I'd expect regular hours. Personally, I've never found my restaurant of choice closed during F&W. (But I prefer to "eat around the lagoon" at the tasting booths, anyway, so it wouldn't have mattered if it was!)
