Our flight to Frankfurt leaves at 9:25am on a weekday. We will be staying at The Hotel Bristol at Kristian IVs Gate 7. If we decided to take the airport train, we would need to take a train to the Central Station in time to catch the appropriate train.
Unless you think otherwise, it seems to be the most convenient and fastest (in total time) to take a taxi to the airport---while normally I would take the train, we are at the end of a tiring vacation.
What time should I order the taxi for?
