No matter how port intensive a cruise is we would still want a balcony. After a busy day on shore it is especially nice to be able to enjoy the departure from your own private space. Also, when travelling with a partner, it is pleasant to enjoy the balcony while your partner is hogging the bathroom.
If we had to chose between a cruise with a balcony or 2 cruises without, it would be no contest. We would always chose the balcony.
