I booked a cruise back in September and got the 30% discount, an additional discount of $50/person, PLUS each of us got our balcony discounts. We booked a Spacious Ocean View Balcony by calling RC directly.
Even better, when I called back earlier this month to add prepaid grats to our reservation, I was able to add the senior discount and the resident state discount on top of the original 3 discounts we got, which reduced our cruise fare by $327 each.
