We had the distinct pleasure of sailing on RCI's Radiance of the Seas from Vancouver to Seward. In a nutshell...
We choose this ship based first on itinerary. We wanted a one-way route to ensure no 'repeats' and to cover the most scenery possible. Second was food. She and I are almost food snobs. And wine snobs. Ok, we really like good food and wine. Based on reading far too many reviews on cruisecritic, I settled on the Radiance to fulfill both these criteria. Touchdown.
The ship is beautiful, and huge. Very clean and light throughout. Our balcony room was perfect. Great use of space and storage. Comfortable bed (we like them firm). Decent size bathroom. Only negative is a shower curtain versus door. While some may feel a balcony is a waste of money, we love to enjoy our room and view and don't always want to dress/whatever to wander the decks. There was not one physical aspect of the ship (save for the shower curtain) that I found lacking.
8618. No complaints except "cloth" shower curtain. Smart use of space. Bright. Nice size balcony. Hallway is accessible yet quiet.
