Can see a Multi pass for €30 includes Acropolis (and the two theatres on slopes)
Others like Roman Agora ,Hadrians library and several others

I am staying down Nikis St and walking distance to lots at foot of Acropolis

Saw some where there is a shop/office on Mitropolis that sells this pass

Any help on this --is there such a shop or do you buy pass at say Acropolis then
decend and utilise it at other sites

This is the official website, which states that the combo pass can be purchased only at the Acropolis ticket office: http://odysseus.culture.gr/h/3/eh355.jsp?obj_id=2384

It would be a good idea to go to the Acropolis first thing in the morning anyway, when it will be cooler and less busy, then visit the other sites.

You can buy the combo archaeological pass at any site in Athens, not just the Acropolis (or at least you could when I was there in the summer of 2015). Perhaps that has changed, but you cannot buy it online or in advance.

There's a ticket office just across from the Acropolis metro station that sells tickets and almost always has shorter lines than the main ticket office at the other entrance, where buses let people off. I've always bought my tickets there and have never waited in line more than 5 or 10 minutes, even in the summer. If you arrive early, then you'll beat the cruise ship crowds and have a much happier visit.

Thank you for advise
Appreciate it
