Of course!! in fact, there was a bit of traffic jam as everyone first got in that area- there were no real lines there just a crowd of people. We sort of edged around the back of the throng and discovered that the passport "booths" at the left only had a few people. Hence- it didn't take so long.
by the way, my husband only filled out the arrival side of the document so the passport control lady had to fill out the other side for him. And, as per the lady who checked us in in Helsinki for the St. Peterline ferry told us, we only put down St. peterline as our sponsoring party or whatever they call it, and there was no problem. I did have a copy of our receipt for our paid two-night hotel stay in St. P.
