I used to be an inside cabin person exclusively.
Then last year, our group of four couples booked balconies
adjoining each other on the Caribbean Princess.
I will never go back to the dark, inside cabins.
The balconies have doors that can be unlocked to open up the
adjoining balconies if you travel in a group like ours. This was a
blast for evening pre-dinner drinks.
I tend to have a better day if I wake up and see sunlight!!
We did not find that we spent more time in our cabin because of
the balcony, but had a better overall cruise experience!!
