Mariner 6658

[1sttimemariner]

This is our first cruise and we're a little confused about what rooms are the best. We were late booking and didn't have many choices for a balcony room with pullout bed. We are currently in Mariner room 6658. Other choices have become available since then and we weren't sure if we should change or keep what we have. What are the best floors and where are the best rooms. We don't care about walking, and are looking for a good balcony view.
