Balcony Rooms on Mariner

[LivetoCruise412]

We are going on the Mariner on 5/27/07 and have already booked a D2 room. But I am not sure what the differences are between the Deluxe rooms and the Superior (besides price) and actually between D1, D2, and D3. Since I only have until 70days out to change something without a penalty and that is approaching I wondered if all you expierenced Voyager Class cruisers could guide me a little bit and tell me good Floors and possibly good Room #'s incase there is something better than what I have. We are currently on the 8th floor and at the back on the port side in a D2 with my kids in a catagory N interior. Thanks in advance for your help:) :p ;) :D
