The ferry is generally OK, so is the service onboard.
However I have to comment on a feature found onboard which is extremely irritating to a shiplover.
Due do vague reasons some places on open decks that should be definitely open for passengers, because - after all - they had been designed as such, are fenced with small gates on accommodation ladders or closed with chains or pieces of rope.
Some ferries, especially the more modern ones, are often designed with very poor, limited access to open decks, especially as far as sites allowing for looking to the fore (and seeing what is in front of the ship) are concerned.
Scandinavia has this excellent feature (by design) that passengers can look fore, while standing on the open deck ABOVE the bridge (exactly on top of the bridge), yet they are stupidly prevented from entering there.
Oh, this "ban everything without a reasonable explanation" culture perhaps..
Even if we assume (but it is obviously wrong, false reasoning), that for some (made up) security resons passengers' access on the open deck NEAR the bridge should be banned (bullshit), then i wonder what the hell is the reason to prevent passengers onboard Scandinavia from entering the aft most and upper most full ship width sun deck with the aft edge being the superstructure wall above the transom stern?...
You cannot see the keelwater trace behind the ship onboard Scandinavia.
Not only the foremost upper open deck is closed to passengers but aft one as well even despite they should be open to passengers as they had been designed as such.
This is probably a security over-reaction driven paranoia !
Also, while on most or all ferries the boat deck is open to the public (passengers) and you can freely walk passing by the boat davits (sometimes separated from a promenade deck by railings) and under the boats, on Scandinavia it is different.
You have small pieces of deck FORE of the boats and AFT of the boats accessible separately by door from inside.
You cannot walk the whole length of the boat deck.
Maybe ferry operators should lock all the passengers in cabins ?....
