I guess I am the opposite. I have no qualms being rewarded for my loyalty by getting priority in terms of reservations at restaurants. Nothing says that they are giving additional reservations, just first choice.
I still think it would be fine to give additional reservations. Yes, I think I deserve more for loyalty than someone that cruises Radisson along with a half dozen other lines. If they don't reward loyalty, it is too easy to lose a good customer to the competition.
