If you are planning a trip to Athens to see the major ruin sites, be aware that the Acropolis is currently under major reconstruction and covered in scaffolding. Photos will not be particularly great as you can't get a clear view of the building anywhere.
You might want to contact a local tour agency and ask when the building work is expected to be finished. And don't assume their estimates will be accurate. Wait until someone can assure you the work is actually complete before planning to visit.
