I never have had a window or porthole or anything in any cruise I've ever been on. We ended up getting a veranda on the Dream this month because that was all the was left. It was amazing! It was the best stateroom we had. And I did go out on it every single day at all different times. I actually snuck out and watched the sunrise and then went back to bed! (cant do that in an interior)
Not sure if I had a choice that I would insist on one... but man did we really did enjoy it!!!
Now my mom who likes to read a book, I dont think she would cruise without one. She loved it too, drinking tea and coffee on the veranda.
