I wanted to report back since I asked a question about booking FP+ with regular tickets and an
MNSSHP ticket. I have a 6 day park hopper and one MNSSHP. I was allowed to book 7 days of FP+ and it DID NOT matter what day or park I booked FP+ for using the MNSSHP ticket. I booked FP+ for October 29- Nov 4th. There are MNSSHP party nights on Oct 29, 31 and Nov 1. I did NOT book any MK FP+ on any of the party days. I did book FP+ for MK for two days but neither were party days. I wasn't sure whether I had to book at least one day of MK FP+ on a party night, but I didn't.
So just wanted to let others know that the MNSSHP ticket when combined with a regular ticket allows you to book an extra day of FP+ at any park, not just MK on a party date.
