Can the Side Entrance (Dionysus Theater entrance, the side entrance is located on the south-eastern side) be used to enter with tickets from the official site? Some places say it's only for small groups and skip-the-line tours. In one official article, they say there is no such thing as skip-the-line. If you already have a ticket, you still have to wait on the line for ticket holders and go through security. Is skip-the-line for real and worth it?
It would solve soooooooo much confusion if "skip the line" was presented as "skip the TICKET BUYING line" because that's all it is. Everyone still has to go through the security line at every site in the known world. That being said, I take every opportunity to purchase advance tickets whenever possible. Otherwise, you're standing in two lines, instead of one.
