Edit: Looks like breakfast reservations after October 3rd are now live for booking at DisneyWorld.com.
Breakfast at Be Our Guest Restaurant at Magic Kingdom has been extended permanently. Currently, breakfast is being “tested” with dates through October 3rd available for booking. Beginning now
August 5th, dates from October 4th and beyond will be available under the usual reservation guidelines. The price is going up to $21.99 for adults and $13.99 for kids. That’s an increase of $2.
I have an extended look and review of breakfast in this post. I’m a proponent of the 8am breakfasts when Magic Kingdom opens at 9am due to the advantage it presents (but doesn’t necessarily guarantee) in getting to Seven Dwarfs Mine Train and the Anna/Elsa Princess Fairytale Hall Meet and Greet before the hordes arrive from the main entrance. For those that don’t care about the advantage or if Magic Kingdom is opening at 8am, then I recommend lunch. It’s probably going to be less expensive and you can take your time enjoying the atmosphere and your food. There isn’t much use eating breakfast here at 9:30am as waits increase at the attractions. In my estimation, at least.
