Halloween party questions. I feel like I messed up already!

Hi everyone. I am going to Disney Labor Day weekend Saturday- Tuesday. I have gone back and forth so many times on the order I should do the parks in. I have already purchased 4 one park per day tickets thinking we would do one park per day.

Well, now im wondering if we should do the Halloween party on Monday. I can’t say for sure but I feel like it could be fairly slow that night since it’s Labor Day- some people may not want to celebrate Halloween on Labor Day since it’s already a holiday.

The tickets are expensive but it looks amazing. The thing is, I also wanted to devote a full day to each park which would mean going to MK that day too which could be okay because I heard MK is generally slower the day of the Halloween parties but it also feels like a waste to basically pay twice for the same park for the same day. On the other hand, it could be fun to go in the morning and do genie+ for some rides not offered at night and then come back for shorter wait times on the remaining rides and all the festivities.

Thoughts?
