We are staying at the Coronado Springs right now, and tried Maya Grill for our first breakfast. It was nothing special, and only a few other tables had guests when we ate there a few mornings back. The breakfast is a buffet, unlike the supper, so you won't have the problem of waiting for your food that the pp had (thanks for that, we were planning to try it for supper one night, and will skip it).
There are a few items, like a mexican fritata that you will find on the buffet here that you won't find in other places, but otherwise it was the just bacon, eggs, mickey waffles, fruit, etc that you get anywhere. The staff isn't particularly friendly and the atmosphere isn't anything special, so I'd pick someplace else before I made a trip over here.
