Hello. Welcome to cruise-chat. My husband and I usually get a junior suite, when we cruise just me and him. One cruise he booked a little late, and could only get a standard balcony. So, I called RCCL, and they had a "wait list" for the junior suites, and they put us on it. I found out we got our JS
, when I called to make a payment via phone. They did not notify me of the upgrade, which I had to pay for of coarse. Anyways, call them! See if they have a wait list for the OS, that you can get on. If you booked via travel agent, they might have to call and request this for you. Hope this helps. Good luck.
