I will be there mid August and it looks like there will be a Halloween party then. Looking at last year, they did have MK after dark (or whatever it is called) during the same time frame as well. I've never been to either, which would you choose and why? Thanks!
I've been to both regular after hours(Aug 2018), villains (Aug 2019), and
MNSSHP(Aug 2019 and many other years)
It really depends on what you want from the party. If you are looking for extra rides, regular after hours is your best bet. Villains is great for rides too, but it does cost a little bit more. We liked the villains show a lot and are hoping that this party will be offered during our August stay, also mid-August.
MNSSHP is a lot cheaper, and a longer event (5 hours vs 3 hours). But, we never bother with rides during this event. The shows, special photos, rare characters, parades and fireworks keep us plenty busy.
Since you've haven't been to any of them...I would say MNSSHP should be your first party (unless you are not interested in shows, FW and parades)
For our trip, our preference is #1Villains, #2MNSSHP, #3 regular after hours. I just wish a schedule was available so I could plan and budget
