Yes, do check more than 120 days out--ours were available about 5 months out.
If you happen to join a multi-segment journey that overnights in your embarkation port, you can't book anything on that first night (our cruise overnights in Rio and there's an evening event that we can't book online, but probably could onboard if we wished.)
