Well Sam, lets see.
45 minutes to the airport (never takes me more than 35, but i will concede)
1.5 hours early at airport (plenty early. about when the ticket counter opens)
1.5 hour flight
45 minutes landing and bags (? sure more or less)
45 minutes into town
5:15, but lets call it 5:30
20 minutes to the station (a little walking and then public transport - people always remember the time to the airport, but seem to forget you have to get to the airport too.)
40 minutes early (not brave enough to try and navigate a new train station, find my track, with much less time than that. Ticketing can be a bit more complicated than in an airport too.)
7 hours on a train
30 minutes, to find / figure out and get a ticket for public transport and get to your accommodations. (that could be short in a strange new place).
8:30 total time vs 5:30 ..... yup, I still fly. But with two people, using taxis at both ends of the flight vs public transportation if going by train, I suspect the flight will cost a couple about 200 euro more. After 4 hours on a train, the plane becomes break even on time. So at that point its style. But I enjoy moving around a lot more than sitting for 7 hours.
