The cabin type & location is vital to us, aft balcony is the one we try to get if the ship has them, the views are superb & if the ship is going the right way you can get a sunrise & sunset into your cabin, we have some lovely memories of sailing into/out of places like Venice. Funny thing I find is that those who say they only use the cabin to sleep /wash/change & never spend ANY time there are always in the cheap cabins that nobody would want to spend any time in anyway!
Another thing I have noticed is that those who never spend time in the cabin, is that they do spend a lot of time in the bars & the coffee bar, most without actually buying anything but just sitting there reading or doing puzzles, therefore actually hogging a seat that could be used by someone who actually wanted to buy a drink.
We have always been the same, seats on planes for instance, why not have a type & position that is more comfortable, hotel rooms too, you can get one at the back over the kitchens or one with a view of the sea & gardens with more room.
Another reason we like a ''nice'' cabin is that we find very little on ships that interests us during the days at sea...like classes to learn stuff "at a nominal fee." We have never found space by any pool on any ship & neither would we want to looking at the crowds crammed together, so our balcony with a view of the sea is valuable to us, after all we can actually see the sea from the balcony, at some of the pools you could be anywhere.
