i recently traveled CGN to FRA airport
first class was sold out (a week in advance) so i had to take second- (to reserve a seat)
the seats were not comfortable (close and crowded) but the car was PACKED with standees
very claustrophobic
and i had a briefcase and carry-on suitcase- its a lot of shlepping and lifting
quite unpleasant
you must reserve seats
but then you are screwed if you miss your train
how much cheaper is your ex-CGN flight v. FRA or HHN? is it worth it?
