Suomenlinna vs Seurasaari?

[dana r.]

For Helsinki, could I do both in about 4-5 hours if I didn't watch the movie or go inside any of the museums of Suomenlinna?

 

How long would it take to do each place?

 

But, if that's not possible, which one would you choose to go to?

 

If I went to Suomenlinna, it would have to be early in the morning before there were any tours or museum openings. In that situation, wouldn't the Suomenlinna experience be similar to what Seurasaari would be like with the walking and the grass minus the tunnels?
