Do you mean QE2?
I was on one leg of the Rotterdam around-the-world cruise and we had terry robes. They were those nice, lightweight waffly ones. I almost bought one, I liked it so much.
Check out the website or ask your TA. I would be very surprised if they were not provided.
Hint: Even if your category of cabin doesn't provide robes on any cruise line, ASK and it will be given.
