We booked a 7a on the Miracle for our cruise in march. Here are some great pictures of the view from a 7a.
Great way to get into a balcony cabin, for less $$. We had a hard time deciding whether or not we wanted to spend the $$ on a balcony cabin, because we know we will be active, and not in the cabin a whole lot. BUT since these cabins are about 20% less than other balcony rooms, I kind of felt it was a good compromise.
I would not recommend a 5a cabin. They do have french doors you can open, but the boat hangs DIRETLY infront of the doors. No view at all. I have heard there are some 5a's that are in between the boats that do have a view, but not an option for us because we needed 2 rooms next to each other.
