TTU cruiser

I've booked my cruise on the Glory for June 20th in a scenic cean view with the early saver package. My class of room 6j is sold out. My question is that if I find that a higher class of room goes on sale, will I be able to call my carnival trip planner and get OBC for the difference between what I paid and the upgraded room rate?

Right now just an ocean view room on deck 2. I've stayed in interior, OV, and Balcony in the past so I know what to expect there. When we booked, we settled for a connecting room b/c it was about where we wanted to be on the ship-port side midship, away from elevators and such. But the more I think about it, the less I'm wanting to share a door with someone I don't know.

I have noticed that the scenic ocean view rooms are also connecting, but my thinking is that room will be less likely to have a less than well behaved children in it.

I am deciding what I am wanting to upgrade to for my upcoming cruise on the Glory. How are the scenic ocean view rooms, do they pale in comparison to a balcony room, or are they pretty good?
