I did, and they said nothing left at Coral Reef for any show.
I SERIOUSLY doubt that it is sold out. There are way too many seats for any show to have sold out already....sounds like it just hasn't been uploaded yet. Garden Grill also isn't showing even the ability to choose a time for the breakfast.
I would either keep checking online, or maybe just come back in another hour and try. None of the shows, including NPH have sold out in an hour....by Wednesday or Thursday maybe.
