We have our regular tickets for Disney and planned on going to Magic Kingdom on August 15th. Then the MNSSHP schedule came out and the 15th is one of the dates. If we decide to splurge, can we do both on the same day? We're staying off site so don't want to arrive early, then leave for a while, and then come back at 4:00. Thought if we came early and then just paced ourselves in the afternoon, we could do the party at night. Our last time there, we stayed for over 12 hours on a regular day and rested the next day. Thoughts?
