That's what I used and really enjoyed it. We stayed the night before at the Hyatt and I didn't need to open the big bags at all.
Pretty much if it qualifies as a "carry on" for the airplane, then it qualifies as a carry on for the ship. I really liked the rollers also and even stacked DH's laptop case on top for easy moving through airports. He doesn't take a laptop but has found the case is just the right size for his carry on.
FYI, I ALWAYS take a change of clothes and my cosmetic bag which has my makeup (unimportant) and our medicines (critical) in my carry on...just in case. Oh and a couple of bottles of water.
