Planning, really

So I have found Tallinn is not the cheap place I had expected. So I decided to move onto Helsinki early. I reworked my travel plans in Scandinavia to compensate for the extra time. Ok, I really needed to work on them, I had not booked anything yet. Should have, I found out the cheap ferry left at 8 in the morning. I had already booked a hostel for tonight in Helsinki (turns out it is the more expensive one, further from the ferry terminal I want), and it is to late to cancel. But I now have the next several nights in Sweden booked. I am going north of the artic circle. Crossing it four times, provided everything works out. Should be quite an adventure. Now I am currently killing time until my ferry at 6. Doing some more research for the rest of my trip.
