Viking Atla or Viking Magni

We are planning our first river cruise in April 2014 after numerous ocean cruises. Is there any difference between these two ships or does it not matter? Both ships sail same day and same itinerary. Been reading lots of threads and they are always so helpful. I am sure as I get more into the planning stages I will be on this site a lot. As always thanks for all your help.

These ships are "sister ships" so there is no difference between the two. We sailed on the Idun, one of the first longships, in April '12, and had a wonderful time. We are now booked for another Viking cruise in 2014. If I can answer any questions for you about the ship, just ask.
