I never heard of any Orion, (except for the one we can see in the sky at night) and even after that long post and I am still clueless. Tell me the difference-you said you learned the difference but you did not explain the difference.
But, perhaps it is because I have not cruised either of lines you mentioned. I have never been on a luxury cruise line. Maybe that is why I feel so confused from your post.
