We went to Fortress Exploration first, so I could leave DH and the kids there while I went to get Fastpasses for Journey to the Center of the Earth. I was able to get 4 PM return time at 11:45 AM.
Photos as we walked over:
The kids had fun exploring the ship and playing with the water cannons.
Here’s the entrance to The Leonardo Challenge (think it’s a scavenger hunt style game), which is in Japanese only – I asked a CM. 
Now I’ll just bombard you with photos because it’s just so gorgeous!
