Actually Grandeur is Vision Class. It was built in 1997 (?). We did our very first cruise on it in 1998. It was a beautiful ship. I heard it was renovated in 2002 (?). Reviews that I have read are all positive. We sail Saturday, Feb.24 on her. Really excited. I suspect you will love the ship.
One thing, you may want to check your cabin location. It may not be a big deal but there are a couple of bars on Deck 6. If you are over one of them you may hear the music, etc.
We are in JS
cabins on Deck 8. I will try and let you know on this thread how it went when I get back. Just remember, the worst day of cruising is better than the best day of almost anything else!
