This was my second ever cruise and it was the first for Disney out of Barcelona in a couple years. My wife and I have traveled around Europe before. My parents also joined us on the trip.
On our way to meet up with the cruise, we were dodging the volcanic activity in Iceland. It made the journey there a little more stressful than it needed to be, but we made it to Barcelona with some time there on our own for a few days.
Embarking was simple and painless once you actually got to the boat. We had taken public transportation to a point where a bus (near the Columbus monument) would then take you to the ship. The bus was not right sized for those with luggage (who wasn't?). If taking this bus, be careful to leaving your items unattended. Police are around, but when we were about to board the bus, someone had one of their bags stolen.
The interior cabin was comfortable. The shower was slightly oversized compared to Princess (interior cabin) as the base made for a little bath for small children. The location was quiet and close to the stairs and elevators but not that you would notice any noise.
