We just went last week and are seasoned and local Disney visitors, and I could not believe how busy it was for January. For our MK day on Tuesday, we did rope drop as planned to get on a couple of attractions without a FP, and then used our fastpasses as everything got busy. After about 10 am, most attractions, like Pooh were 25 min wait or more, and then after that it just got busier, up to 60-80 minutes, at which time we went to the shows instead of rides (Philharmagic was about a 20 min wait). We still managed to get quite a lot in that day, but without the fastpasses we would have skipped Haunted Mansion and Pirates, two of our favorites, and would have missed out on Seven Dwarves Mine Train. I would use whatever you can book, and then hopefully won't have too long of a wait for everything else. Going on rides during the parade or fireworks is usually a great time with less waits as well.
