We wanted to do a transatlantic crossing. We liked that there was a minimum age...no youngsters running around and playing in elevators! We liked the idea of free beer & wine at lunch and dinner...we did not need the drink package! And having the laundry facilities was a plus. Here are some of my thoughts...and I know I'm missing some tips...
The cruise was a pleasure. I liked that it was very informal...literally no "formal" nights, but you still had to dress appropriately for the "dining rooms"; you had the World Cafe buffet and the Poolside Grille if you did not want to get dressed.
Seasick? I was worried about rough seas, but I did not feel sick at all. I got the "patches" from my pharmacy, but never used them. I used "Meclizine" ("Bonine"), taking one at night before bed. It was just enough to keep me feeling well and not making me sleepy. Check with your pharmacy and see if you can order a bottle of Meclizine instead of spending $$$ on the blister packs of Bonine. Years ago I got a bottle of 100 for $7.
Cabin was roomy and had plenty of storage. We wanted for nothing...but if we did, "Darius" and "Vive" accommodated us! We were on the Port side of the ship, almost to the back. Being on Deck 5, we did feel some of the rocking & rolling, but it usually helped us sleep!
We did the free "walking tour". The guide was knowledgeable, but chatted more about some of the food than the area. We walked quite a bit and got to go in the cathedral. We wandered the town on our own later.
We took the shuttle into town. The system for the shuttle did not appear to be well-planned. They did not run in to town that often. And with the "Fallas" festival, there was lots of traffic...and people. Check out the town before you go on the ship to take advantage of seeing lots of the buildings in this town. We sat in a street side restaurant and enjoyed some inexpensive beers and the throngs of folk passed by after the 2pm "burning" ceremony.
