The line to the Bakery is CRAZY long when the park opens. We did all of Fantasy Land first, then by 10am when back to the Bakery and it was empty. Plenty of food left (they do run out of items) and lots of seating.
I don't think I would ever waste precious park time in line at the Bakery right after rope drop. Go grab a FP and see a few headliner attractions first, then hit the Bakery once it clears out.
It's such a cute bake shop. I really enjoy sitting there and looking around at the decorations.
PS: On a hot day try the frozen latte.
