We will be in Athens for two days at the start of our Greece vacation. One of those days is May 1. I know that the museums and archeologicial sites will be closed, and we were planning on simply exploring the old neighborhoods around the Acropolis. Is the funicular at Lucabettus Hill open on May 1? We don't mind walking and we're particularly interested in architectural building styles. Any suggestions on things to see and do would be greatly appreciated.
