Background Information: I am a solo traveler, male, mid 40's, and have cruised on Royal Caribbean several times previously.
Travel To Port of Embarkation: Though I had not pre-booked, I had no difficulty at all in adding myself to the RC-supplied bus-transfer group being collected at the Oslo airport. The bus ride was $36, and took approx. 45 minutes. The express train back from Oslo was quick, easy, and an even better deal.
Check-in: A bit confused on the pier—perhaps because of the windy, rainy weather...?
