We've cruised with RC four times, and to be honest if we could find an RC ship on an itinery similar to any other ships we would choose RC.
The food is fantastic - probably better than Thomson, certainly more locations to eat and a better variety.
Not done Thomsom but RCI are a league above NCL. Think Aldi to Waitrose.......Wilba.
Have to agree with both comments, have only cruised with RC before, and looking forward to our 4th cruise in June 09. Food is first class, plenty of choice, plenty of places to eat. Nothing more to say!
