Just back from May 4th NCL Baltic cruise with 2 night stay in Copenhagen. Definitely an intensive destination type cruise with much history of the region.
CPH: Stayed at Scandic Palace. Clean, updated historical hotel with mix of old and new. Room location is key as to noise level. Room 223 is located above the samll street behind the hotel which is subject to out door cafes that are open and drinking til 1 am. thus it sounded like someone was in our room half the night. Hotel location is great. We walked to Tivoli (you can get hand stamped for evening return)during afternoon for beer and outdoor concert then returned after dark to enjoy the lights. Taxi ride from airport $230kr.
Embarcation day: Taxi from hotel to ship for 6 and luggage was 242kr. NCL staff friendly and directive so on ship about 1 pm and the cabins were ready.
