Hi...My first ever cruise was on the Spirit. We were on the same deck, on the opposite side of the ship as the room you are looking at. I don't remember a mini-fridge in our room, but there was a safe. I was very surprised at the roominess of the bathroom after hearing some horror stories from friends of mine.
Our only complaint about the room was the noise in the morning. We were directly under where they store the lounge chairs for the pool and were woken most mornings around 6:30 to the sound of chairs being moved across the deck. Shouldn't happen where your room is located.
We found lots of little hideaways on the ship, but our favorite was Henry's Pub on deck 7. We spent lots of time in there and made friends with the bartender.
Hope you have a great trip...
