We've been here since 1/7 and crowds have been great! We used TGM's advice for best days and also his touring advice and have had minimal to no waits all week. The only times we waited was when we arrived in between shows and were waiting for the next show time (like Philharmagic). A lot of the FP machines aren't even open because of crowds. We have walked on just about everything, gone on several of our favorite rides multiple times in a row etc. The only things I can think of that weren't a walk on or less than 5 minutes were POTC at noon (sign said 20 minutes but it was only about 10) and Kilimanjaro Safari (sign said 20, was less than 10).
We have mostly hit the parks in the am and stayed only half day, sometimes returning at closing or close to see fireworks and hit last minute rides. When we leave the parks each day they do seem much more crowded (around 2pm usually). I would definitely go this time again!
