For those who are not aware, the CM appreciation day on 30 January has had a couple of impacts. As mentioned, EEH for 29 January is now at AK. What I don't think has been mentioned so far is the new AH party for HS also on 29 January.
I'd been disappointed there was no AH party for HS during our trip, and had actually been toying with the idea of the LLPP. Now there's an AH party, we'll do that instead

AND we can still do EEH at AK that night too! AK EEH 6pm-8pm, then HS AH party 9:30pm-12:30pm.
I'm super excited that we now get 'special entry' to ALL 4 parks during our trip! AH + EEH at MK, EEH at EPCOT, AH at HS and EEH at AK
