Do you need an HC bathroom? If so, a gty. booking will not work for you. It would be best to take a look at the deck plans, and book the cabin that makes the most sense for you.
If you don't need an accessible cabin, then the GTY is a good cost-saver. When RCI says "partially obstructed", it's usually less than a post or perhap lifeboat covers below you. You will still have a view!
