We had the Fantastica experience, which was why I was surprised when we got ATD. The entire Seashore restaurant was ATD on my sailing, so it seems like they opened it up to more than just Aurea guests.
As for the weed smoke, I do think that the low prices are most likely the culprit. I will say that prices since I booked this cruise (in Jan) are no longer as “bargain basement,” so maybe that will help.
