Find Your Cruise
I'm not qualified to comment on the sizes of the suites, but would comment only that we were on Ventura last July and from sitting at the stern at decks anywhere between the restaurants and the terrace pool, I'd willingly go for a midships cabin/suite just to get away from the vibrations that seem to beset anywhere aft. Closer to the pointy end the better, I'm afraid; you know you're at sea, but in a serene and pleasant way.
(A230, looking down on the mini-suites!).
