We are two seniors who will be in Stockholm next month. As we will be tired and have luggage I am concerned about using public transportation. I have read about taxi scams but wondering if we should try the Arlanda express ? We will be staying at Marriott Courtyard. Another question, we arrive on Wednesday and depart on Sunday is the Stockholm card a deal for such a short visit? IKEA is not too far from us but doubt if I can apply there and perhaps a senior rate would be best?
