Tips are for excellent service. How therefore can you pre pay ?- this is a rip off. don't let cruise lines get away with it. As for the weather try 'www.bbc.co.uk/weather' and follow the links to each country you are visiting. Alternatively, put in 'temperature in Corfu in may' for example. you will get lots of hits. follow this with similar research of the tourist boards for the places to visit when you are there. It always works for me. Also trip advisor is a good site for recommendations as to what to see/where to go in various ports.
I too am not in favour pre paying for a service 'not yet received', however due to the state of the Dollar/Pound, if you paid the recommended amount whilst on board it would cost you about £47pp. If you prepay, it will cost you £34.50pp. This is due to the fact that RCI have not yet brought their Stirling prices in line with the new Dollar rate......Wilba.
I would never pre pay. On our last cruise, the head waiter was unconcerned and inconsiderate when a waiter spilt a drink over my wife's evening dress. He received no tip but the other waiting staff benefitted. By not prepaying, it does give you the opportunity of sharing the tips according to the service you get.
HI, I'LL LET YOU MAKE YOUR MIND UP ON THE "TIPS",see previous comments.I did this trip late april/early may, this year..Weather in venice was good about 25deg/c./croatia/santorini/turkey were all about 25/26 deg and sunny.Only downside was on board where it was windy everyday, and evening walks on board were too windy and cool.At least during the day the covered pool/jacuzzi area was a great boon when windy.Pleasant ship by the way.
