We ate from the complementary breakfast but brought it back to our room. They actually opened it early (3am) on runDisney race days, which I thought was nice. I didn’t notice it being any worse than those things usually are but I hate them wherever they’re offered. They are convenient though.
We also ate at the Grand Californian quick service one morning (after we finished the Family 5k) just so we could get our fix of Mickey waffles.
