Hi circleboy,
We were on a portion of that cruise in 2004 and did fine without a laptop. However, the computer room stayed busy and I usually had to wait for a computer.

I think the answer depends on what you will do with the laptop. If you take lots of digital pictures and want to download onto your laptop, you might enjoy taking one. If you're computer dependent for business or financial purposes, you might like the convenience of a laptop. If you write or enjoy documenting your trip, a laptop makes it so much easier plus you can use it on the plane.

My next cruise is this weekend and I am taking a laptop. Made a poor purchase so I'm taking a HEAVY laptop. Next time I'm looking at the lightweight Sony's.
