Royal has GREAT returning cruiser perks. I'm Gold on Royal - after my next cruise I will be Platinum - and I already get more perks than being Gold on Disney gets me (well, my DH is Platinum). You have to get much further in NCL's and Princess's programs (only sailed on those) than Royal's to get benefit from it.
I love the 10% off on Disney but that's pretty much it.
