Won't it be absolutely packed?
We're trying to avoid really busy places too (hence my question about if you can walk down the road a bit). It's just better in our opinion with less people there. A reason I avoid Harju stage.
On that point, I saw your great post a few days ago about best places to go on stages on Friday.. You seem experienced about the stages and places for spectators.. can I ask where you think are (or could be) good but also quiet? The fewer people there the better. We can walk if we have to!
We found this place in 2016 on Horkka stage and it was really great
