Audiobook the whole thing! Re-reading is hard, but taking the slow path with audiobooks is great. Personally, I've had some of the best memories of the books while listening to them while hiking. Especially for fantasy books, walking/adventuring while listening is great fun.
Re-reading is anything but hard. It's like slipping back into my 17 year old self, complete with breaks to jump around like an idiot because I'm so hyped and I need to expend a bit of this pent up energy before getting back to the whole reading thing.
