H and A, I don't think service is any different than it was, but my comments are purely on the reaction that is received when people talk about tipping on this and other boards is that you have to tip. If you don't tip, you are either cheap or mean.
I must admit I am still trying to figure out the type of service people require. I want my room cleaned and my drinks and meals served. That is all I require. I tip based on that expectation as well. Do what you are supposed to and get your tip, don't do it and your tip is reduced. If tips were included, then complaints would be in order then.
I also fully realise that if tips are included, the cruise cost goes up by $10 per day.
