I thought it might be helpful to compare the 2 as we were on the Seaborne Sojourn last summer.
Ship/cabin
Sojourn is newer ship with a contemporary understated elegance. It remained me of a Four Seasons hotel. Silver Wind is an older somewhat dated ship. It was refurbished in 2013 but I am not sure what t they did. There was no movie streaming in the room but a DVD library, kind of like going to Blockbuster 10 years ago
