They also have one of those "make your own pancakes" for kids that involves pressing a button and two pancakes eventually come out on this conveyor belt system. I was with a 4 year old this weekend at the Royal Pacific character breakfast and they thought that was very fun.
Also, on the way to the water taxi there is a special Bula Bar & Grill Coffee Express stand outside from 7-10AM serving quick options to grab and go. You can find the menu here:
