This morning, they had the fruit bar, pastries, scrambled eggs, bacon, pork patties, hasbrown, etc. The most “standard” stuff. Enough for us.
Special stations (ex. English breakfast) or custom eggs, etc. were closed.
I was able to upgrade only 1/2 to premium a few days ago for my July Summit cruise where we both had Classic package as part of the cruise fare.
The rep on the phone just asked if she should upgrade only me, or my wife as well.
I paid $20+20% though.
