Is there a difference between the rooms on the main deck, upper deck, etc in terms of quality or desirability?

Well the Inside Cabins has a lovely view of a wall (you will not see daylight AT ALL!) The Ocean View you can see out. But to answer your real question, I believe the only difference in the cabins is how high above sea level each deck is. Which is reflected in the price increases. I guess it’s a better view? Closer to all the activities?
