Alright, lemme see. One option is taxi but that will be a bit expensive from the Helsinki/Vantaa airport. Thats the fastest tho, taxi to the hostel, drop off yer stuff, then tram to Nosturi which is not too far from the center(i have walked from kamppi to nosturi in about 25 mins drunk).
Option two is the airport bus, much cheaper, its like 3.4 euro, and takes you right to train station....but you might have to take your bag with you to Nosturi, cos that will leave us just enough time to take the tram to Nosturi. This option is risky, cos I am once again doing photo like i said for Norther, and the show is Thursday, which means its starting a little earlier.
Option 3 is a taxi straight from the airport to Nosturi with your things. Most expensive, but fastest and most direct. Probably only necessary if the show starts way early.
Option 4 is the show starting way to early, before you arrive in Helsinki, me going to Nosturi, handling the photo for Norther, leaving area, you taking the airport bus to the train station, and me picking you up from the train station and taking you to Nosturi to at least catch Finntroll and then proceed to get you drunk.
But i shall find out the show starting time(in Finland, many of the shows start on time unlike the US for some reason). Then let you know so we can plan our best attack.
Ive done this before one night when I had to work, leave work for Dissection, and come back to DJ the afterparty. I even had song lengths written down to try to figure out when I had to leave work to get there in time.
The last and final emergency option is you arriving as soon as the show starts. In that case, take a taxi to Telekkatu 8 which is Nosturi, ill meet you outside and drag you in.
