How do you make reservations? I'm trying to reserve roundtrip ferry passage and 4 person sleeping room from Stockholm to Tallinn and back August 13 and 14. I tried to call the phone number listed in Rick's Scandinavia book and I just got a recording with no way to make the reservation. So, now what?
You could try the Tallink/Silja website.

I haven't booked used the website. I've taken this route twice, but both times I bought the ticket in Stockholm.
