Cruising mid May and will be returning to Copenhagen. We will need to get to the airport on the quicker side, as our flight leaves at 12:15---it was that or wait another day, which we didn't want to do. Norwegian rec. at least 6 hours before flight and we have 5 hrs, 15 minutes. Should we take a taxi or rely of the transfer offered by Norwegian? Does any one have experience with this? Thanks.
