They often do have an all day BBQ at Easterfest, though by all day they mean it will start about 4:30 or later.
It was a good day but yes, it was quieter than previous years. That said, I usually stay the night so I'm there later and it gets very busy after 8 but this time I was heading for the train at that time.
Easterfest is the bigger one though. The breweries themselves are there and it attracts a lot more people.
