BACKGROUND:
My wife and I are both 50+ and now cruise at least twice a year. We've cruised on Princess (Platinum card), Carnival (Platinum card) and Celebrity. We're easy to please, always use a AAA travel agent, always book a balcony cabin always on the lookout for a good deal. We normally book an aft cabin on a deck or two below Lido and the casual buffet eateries. That way we're close to the food but always use the stairs so we do get some exercise {*_*}. Since I am a former teacher (5 years was enough) I decided to give letter grades for each component I reviewed.
ARRIVAL + NYC:
Plenty of storage space BUT closets are across from the bathroom so you have to be careful opening the bathroom door and closet doors at the same time. There's a thermostat on the wall for changing the temp in the cabin. Relatively low noise level.
