I was at MK and AK this January at CL 9 with overall crowds being a 10. Having touring plans made ahead of time helped tremendously.
The worst part for us at MK was trying to get through the crowd after Wishes because we were in the middle of the hub.
My touring plans for AK were not in order before my trip (I forgot to fix but did have our FP’s booked) and the AK day was a little more chaotic. That park was predicted to be a crowd level 4 so I thought we’d be “ok” and crowd level ended up being a 9. We didn’t get to do everything but survived and still made the top attractions.
AK felt more crowded to me over MK at a level 9 – it was apparent as soon as I walked in bc my patience was highly tested and I could feel it all day! We didn’t rope drop on any day because we had marathon early mornings for half our trip.
I will add that I see crowd level as the amount of people around me (I know that’s not what the CL goes by on TP), but that is because my own stress level depends on how many people I have to shuffle through/around, not the standing in a line part.
