I would say medium maybe…. This was my first trip to DL in 25 years, so I don’t really have much to compare to. We had some waits for sure, Radiator Springs Racers was 90 min I think, but we could do lots of things with a short wait too. I rode Luigi’s and Mater rides in Cars Land over and over and were almost walk ons while the others were in line for RSR. Sorry, that is probably not much help at all!
ETA: I would absolutely go during this in between time again, because I thought the crowds were very manageable!
