I'm flying into Helsinki next week, and need to get to Turku (and then back again in a few days). I've looked at some options online (train and bus), but wondering if anyone has any first-hand information - and I'm considering travel time, comfort, and cost. I notice that Onnibus if far cheaper than the other options, but wonder how comfortable it is (because I'll probably have to be working on the way, on my notebook). Also, for all options, if one purchases tickets in advance to get a lower fare, and then one's plane is late, does one forfeit his ticket?
Thanks for any information.
