We have completed many Transatlantics including a previous one on Jewel of the Seas. We particularly like the relaxing sea days and getting to know other passengers, so joining activities onboard is a big plus for us.
Embarkation and travel to San Juan was part of the package was well organised as was the disembarkation and return journey from Rome. We arrived the day before departure, giving us a little while to explore San Juan.
Excursions organised through the ship were on the whole, very good. We did have one poor experience but upon return to the ship we raised with the shore excursions team and they investigated, came back to us very quickly and resolved to our satisfaction.
Cabin was spacious with a great sized balcony. The only negative point I would make is there is some noise from above very early in the morning, so probably not great if you are a light sleeper or like to sleep in.
