We like the bigger balcony also and really like the half covered, like the Caribe deck.
We were able to use our deck almost every day, because if it rained a little, our table and chairs were under the covered area.
We sailed the opposite of you, from San Antonio, Chile to Buenos Aires. Loved the port side. If I were going the opposite, like you, I’d book the Starboard.
Amazing views.
The large balcony is more important to us, than having the extra room inside the cabin. I do like CC mini’s, but sometimes the balcony is smaller, or uncovered. I do like the midship location though.
