How long did it take you to play The Legend of Zelda: Ocarina of Time?

I'm getting the 3DS remake tomorrow, and it'll be my first time playing the game. I would love to do a non-stop run and finish as soon as I can, but I have a long trans-Atlantic flight in about 2 weeks. I want to have at least 10 hours left of gameplay left for the flight, so please tell me about how many hours it took you to beat the game so I can regulate how much I play over the next 2 weeks. (The categorization of the question is a little off because my 3DS is being glitchy and not letting me pick any category other than the suggested ones, but it's close enough)
