I'd stay with the L shaped cabin. We like the layout much better. It's nice to have the bathroom back by the balcony door instead of in the hallway by the cabin door. We were in cabin 7419 on the Victory in April and loved it. FYI...the higher the deck the move ships movement you will feel.
PS THe bed is also a queen size bed in room 7419, not 2 twins pushed together.
