Are you asking if it is busier in the MK on a non-party day? 100% yes!
You can go on a non- party day but you will wait in substantially longer lines than on a party day. It’s your choice but not something I would personally choose to do unless
A) I wanted to see the fireworks
B) It was the only day I could go.

To help put this into perspective, this would be the average wait for an attraction like Seven Dwarfs Mine Train:
2: 18-48 mins
7: 49-77 mins
For us, we plan our MK days during party season
on party days due to the amount we can get done with very little wait. Everything is less crowded (pathways, food, restrooms, etc) which is the game changer for us.
Totally up to you if seeing AK after dark is worth the longer waits. Is there not any other day you can go to AK? It gets dark earlier in Dec so often guests can see Pandora after dark.
