I think you will find that the size of cabin 6052 category A4 is 307sq.ft. For a definitive answer I suggest you contact Cunard direct. The cabin I stayed in had plenty of wardrobe space, but hardly any drawer space. This has been something mentioned by many previous passengers. Maybe Cunard have taken this on board (excuse pun) and adapted the cabins. Luggage can usually be stored under the bed, unless exceptionally large,if so,the steward would normally find storage space somewhere away from your cabin. Have a great cruise.
Thank you both sorry for late response to been busy decorating etc and hadnt looked at the site for a couple of weeks. I had contacted Cunard and they confirmed the 307 sq ft.
To reviewer Stone: from your comments it would appear that you have sailed on the QV, in your honest opinion what did you think of her (a) as a cruise ship (b) public space areas (c) entertainment and finally (d) food and service.
Having just completed a Caribbean cruise in early March on the QM2 I think the QM2 will take some beating.
Appreciate a honest (even if detrimental) comment regarding the above.
