Have been in February, which I assume is a lot like January. On the weekends you will still need fastpass. During the week, especially Tue-Thur you won't need it much if at all. Also, on slow days sometimes they don't even offer fastpasses. Even our last trip in September, they didn't uncover the machines for Splash Mountain until later in the day on a Saturday. It's a great time to go but more things will be down for refurbishment. Also, Iceskatejen is right about that fastpass thing. You can definitely get one for the same ride in the same day (once the original's return time has come up). I too had a castmember of all people tell me you only got one per ride per day! I have never seen a system so misunderstood by so many! Parade of Stars will probably run once a day during the week and twice a day on the weekends. When it gets closer to your time, just log into Disneyland.com and click on calendar to check your specific dates. Have fun!
