When we were younger, an inside was just fine with us. In fact, our very first cruise in 1987 was an inside with an upper and lower berth
We used the cabin to sleep, shower and change. Now, 24 years later, we spend far more time in the cabin so at least want an ocean view. Our last cruise we had a balcony for the first time and it was great but we sail in 8 days in an ocean view again. The ship and itinerary were important to us but a balcony was not in the budget. An ocean view cabin is way WAY better than no cruise at all in my books.
