Very funny, Norm
Welcome to Cruisemates!
My opinion may not be worth much since we've never sailed either of these lines, but from what I've read on the boards I agree with Kuki.
Celebrity is a "notch above" Holland America. I think the space ratio and the crew ratio would be about the same. Of course the space ratio would depend on which cabin you book (unless you're talking about the whole ship). To us the crew ratio doesn't make any difference as long as they're helpful and friendly
IMO, Celebrity is more formal than Holland America if that makes a difference one way or the other to you.
Have a wonderful cruise, no matter which line you go on!
P.S. Our favorite line is Princess
