That's all I can think of off the top of my head. In my opinion though, I wouldn't get a counter service breakfast in MK that week because it's so packed. I'd get something quick at the hotel as to not waste time in MK.
MS Bakery featuring Starbucks will have breakfast sandwiches and pastries. You an also try one of the breakfast waffle sandwiches over at Sleepy Hollow or move into Fantasyland for a cinnamon roll over at Gaston's.
Never been to Casey's for breakfast (never eaten at Casey's actually, not really my thing).
None anymore. JMO. Didn't really like the waffle sandwich, not a cinnamon roll fan and Starbucks is just a couple blocks from my house.... nothing special.
I wouldn't waste a CS credit at MK for breakfast. All we have been able to find in years past is coffee and a muffin at odd spots around the park. I did like Sleepy Hollow but not for breakfast, we went for a night time snack. But it all depends on where you are staying I guess. If there is a good food court where you are staying I would use my CS there instead of MK. Or I hear the Contemporary has a good food court and is walking distance to MK.
