We booked a Concierge Class for our first ever Transatlantic Crossing. (Actually we had originally booked a Sunset Aft Balcony when my husband had second thoughts and we were able to move to a CC3 for 100 less per person). We really enjoyed the little extra perks like the Canapes that we could enjoy on our Veranda with wine brought on Board in Barcelona, nicer robes, pillows, and lounger ottomans etc....
Embarkation in Barcelona was a little slow due to a delay, but we are always prepared for craziness on embarkation.
In fact, we were prepared for a lot of little "blips" due to the fact that it was a new ship - really there were very few. The food in the MDR was the best we've had on a cruise ship in a while. We tried all the Specialty Restaurants and they were a lot of fun, though only in Murano did we feel that the food was truly exceptional. The experiences were so fun however, we would do them all again.
1257 - perfect location!! Close to elevators, so not a lot of walking, but not so close to be noisy. Cabins above and below so very quiet!!
