This was our second trip on the Jade (previous 12 days Med) and followed on from a 7 day Mediterranean cruise on the Norwegian Epic which finished in Rome 3 days earlier.
Upon boarding the Jade it was a relaxing feeling of familiarity, almost like coming home! after 7 days on the huge Epic the smaller Jade felt much more personal and welcoming. While the Epic is a great ship and the staff wonderful the smaller vessel just feels a bit more relaxed.
Embarkation - simple enough. Take people mover to port and walk a few hundred metres to the ship. We were there around 1pm and it was quiet enough. On board within half an hour.
Cabin - we had a balcony on both the Epic and Jade, so can make some comparisons. I definitely preferred the Jade cabin, even though the Epic was more modern. The bed was bigger (Epic rounds at the corners) and more comfortable (Jade have a luxurious padding between bed and sheet). Seems to be more room on the Jade and after being in both can confirm that the Jade bathroom design is more preferable.
