I've been twice to the
MNSSHP and the first times we were so excited not to have long lines that we spent much of the night riding the attractions. But we missed many of the special things that only occur during the party such as the dance parties, special meet and greets, etc.
The next time, we planned ahead of time what special party-only things we wanted to do and had a blast! After the last parade, as everyone else was running toward the exit - we were running toward some of our favorite attractions! We were able to ride all our big ticket attractions within that last hour and we even rode Splash Mountain several times in a row as the only riders on the entire ride! So do the party stuff first and don't run out after the fireworks! You can get so much done at the end of the night as the crowds really thin out.
