I used to go to Holland and Germany from France back when I was living there and even though at the time it would take longer (slower and less trains) the trip was totally worth it: I even met people who eventually became friends.
Now, when flying from Spain to France (every couple of years), even though the flight is less than two hours, the entire trip is more than four, and much less fun or enjoyable as far as I'm concerned. For the moment, it's just easier to take the plane but that's supposed to change... We'll see.
