Yes, that is my understanding as well. There's an excursion they're putting together and they're trying to figure out how to get people their travel passes before that even, because the plan was to have people pick them up with their membership badges.
We are arriving in Helsinki at 2:50 pm local time on Tuesday, staying at Citykoti Downtown Apartments, maybe the Punavuori area? (There's a big market we plan to visit in the mornings and it's not too far from there.)
We fly from Helsinki to Amsterdam on Monday August 14 at 10: 40 am (and then from Paris a week later back to the US), so we have some time Sunday night to socialize with anyone still about. Will there be a planned BWB gathering somewhere at Worldcon? I'm on a few panels, so if nothing else, people can track me down that way if I can't find you!
