I've never had a Hampton breakfast I'd give more than a 6, but I've never had one I'd give less than a 4 either. Of all the things I've complained to the front desk about in coming up on 8 years of 10-20+ Hampton stays per year, the breakfast has never been one of them. Even the eggs that so many complain about have never been so bad I couldn't eat them or have even avoided them.
I do sometimes degrease the sausage a bit with a slice of bread, but I blot greasy Pizza too, so that's just me (I don't mind grease IN my food by any means, but it's a little much when it's just ON my food).
It's not the buffet at The Bentley, but I've never walked away from a Hampton breakfast (though sometimes past it to the grab-and-go bags when in a hurry).
