Embassy Visits as PD?

I was in the Swedish Embassy on Wednesday and saw a flier for this event. Looks like a good event;

It is an open house on Saturday May 9th from 10am-4pm at the EU nation embassies here in DC, they have shuttles to bring people on different routes to visit embassies. Its an opportunity to "look behind the gates."
What do you think? Is it PD? I think so, they are connecting with a foreign public and its a good pull technique. People choose to go into the embassies and perhaps they'll walk out with a more positive view of the nations of the EU.
Any thoughts? and Anyone going to go?
