I didn't feel like a 'guest' on Crystal when I had to sign chits for drinks. It was particularly annoying because I was sailing with a group of twelve. They also had obnoxious plastic drink advertisments on the tables on the deck and the Lido grill a la Dennys. This is why I have never went back on Crystal and have yet to sail Radisson. Although I really want to try Radisson, I like the ambience of all-inclusive, so I'll "vote with my feet" and stay with Seabourn and Silversea for now.
