Although we are from the UK and were originally looking at European lines for a first time cruise our agent recommended Celebrity above all the others. My wife and I have taken his advice and booked for a Western Caribbean departing 2nd January 2004. . A wee bit confused on tipping. I know there are tipping guidelines but in other reviews I've read some experienced cruisers advise tipping extra at beginning of voyage to ensure good service. Is this sound advice?. I had intended wearing a dinner jacket (tux) but again there appear to be differences of opinion - guidance needed from anyone who sailed on the ship. Advice etc welcome on above, and anything else, which will make sure we fit in whilst on board.
