I reread your initial message in which you mention it's your first visit. My children are scared of the costumed characters (like Mickey, Minnie, etc.). When they were in the Rainforest, the youngest was really unnerved by the close proximity of one of the audioanimatronic apes. If you don't know how your children will react to characters, the princess breakfast ought to be a good ice-breaker. My children, though scared of MM, have always enjoyed human-looking characters.;-)
The good news is they are warming up to MM. Still need some warm-up time, but not as scared as they once were.
