Indoor with walkview view VS. ocean view?

I'm going to cruise with Carnival in June and I'm not sure of wich cabin to choosed - maby anybody can help me?

There is a interior with walkaway view for 1460 $ and ocean view for 1500 $ som almost the same price. The interior is in deck 6 and seems bigger but it's the last one and there fore I dont think I can use the price protection.

The ocean view has a lots of cabins still avaliby som if there is a pricedrop I can use the price protection to earn some money...

How to do? Any ideas?

Have a nice Day :)

I would rather see the sea....
