First things first. We are Seabourn fanatics and have sailed on month long voyages with Seaboun. I thought I'd share my comments about Silver Spirit that we sailed on for Christmas and NYE.
We started cruising on the larger, bigger (low scale) lines such as Princess, P&O, NCL and RCCL we then found Seabourn and became instantly hooked. I've written a few reviews on Seabourn Legend if you want to read them.
Silver Spirit was a choice that we made last year due to the heavy discounting that Seabourn could not match. It was a difficult decision to make, and we do prefer the smaller ships.
