Lots of useful info posted but could use a little more. I am traveling on a 5 nt Carnival Imagination cruise to W Carib. Is there a differance between buffet dining and seated dining? We do not want to tip the Maitre d and other staff if we do not have too. We would rather directly tip those who help directly help us. Would it then be a better idea to remove the automatic tip and tip ourselves??? HELP !!!!
