Boo to You parade and HalloWishes on 2 non-party nights?

Just starting to plan a trip in late October and saw that TP has Halloween party events scheduled on 2non-party nights, October 28th and 30th. Is this an error? Or will Disney be showing these events to the general park goer on those nights? If so, is that new? Sorry if this has been explained elsewhere.

I noticed the same thing and was wondering as well.

tagging @len for this one.
