If you are planning to dine at 'Ohana before a
MNSSHP this year I recommend attempting to get a dining ADR ASAP. It is an extremely popular restaurant and has become increasingly hard to book. Walk up's are rarely taken now

. We dine there every WDW visit, and actually did it before a MNSSHP a few years back. We had a 5:15 ADR and were able to eat (food is brought to your table family style, meats are brought by on skewers), go back to our room at the Poly to get the girls in costume, and arrive around 7PM for the party. Good luck!
