We book insides with the last 2 and the upcoming being PT class on Carnival. Actually an outside but only with portholes at the price of a class of insides. We like those layouts but not having windows is no problem for us. One time we had a balcony and other that when at dock we did not use the balcony, and it did not mean we spent anymore time in the cabin so balconies are not worth it to us.
