Actors have slowly very slowly been added. It first started with the addition of traditional Beer Maidens in Oktoberfest. They served beer at the stand by the pretzel shop and they had real accents and outfits. Then it was the Vampires at Open Casket. They were in full costume with supposedly real Transylvanian accents. Now they have French Waiters working at the Crepes & Coffee stand that greet you in French and assist you as needed.
Yes, Crepes and Coffee stayed.
Those are actually faux ivy vines with patio lights attached and some random bundle of twigs tied up. I can see the logistics of having low hanging garland being an extreme issue. How will service trucks get through the area? So honestly, I don't think having anything low hanging is ideal especially over a main pathway. Perhaps just patio lights at the Crepes and Coffee stand only or around the sides of the main pathway but not going over the pathway.
EDIT: They added the twinkling lights from Christmas Town to some of those faux vines which I think is a neat effect, just the vines should go now
