On the cruise you can always get tea, coffee, water and in the WindJammer there is old fashioned cloudy lemonade (yummy) and two flavours of fruit punch. I am not even going to go near the subject of tipping - if you a search on this site you will find it has been mentioned just once or twice...
I have just got off the Navigator of the seas, prices were $7.50 dollers for a pint and around $8 -9 dollers for a spirit and a mixer, not cheap, .
$5.50 per pint and 8-9 dollars for spirit/mixer EXPENSIVE!!! even prior to recent changes in rate of exchange. (Independence of the Seas) October 08 Canary Islands 12 days.
