I'm not sure Radisson and their casinos are complete partners. I chatted with the casino manager quite a bit while I was playing 3-card Poker, and he was bemoaning the fact that you can't get cash in the casino, signed against your onboard account. He wanted everybody to put that on their suggestion card, because he said people get quite upset when he and his staff have to tell them no. I know I've seen people say they could do that on other lines, in threads at CC.
