One of the benefits of the breakfast is being able to meet the characters without having to queue in the M&G lines. It can be a timesaver that way.
With your 3 breakfasts, you'll cover the Winnie the Pooh group; Donald, Daisy, Mickey Mouse and Goofy in Safari gear and the Princesses.
I've had breakfast at both Tusker House and Crystal Palace. Both offer a decent spread. I haven't done Akershus.
Which one were you thinking of dropping and which dining location were you thinking of adding?
I was thinking Tusker House because I wanted to keep Crystal Palace to be early into the park & Winnie & Akershus for princesses & photo package. But then as we don't have a lot of time at DW it would be good for kids to have photos with Donald & Daisy as they haven't seen them before
