What cruise? What ship? What cruise line?
There is an additional charge for single passengers, and this varies from cruise to cruise. Very occasionally, you might find one with no charge. You can fly from any airport you like. Flight tickets can be organised the the cruiseline, which is the normal case on a "fly cruise" or you can book a "cruise only" and organise your own flights .
Yes there is an additional charge for single passengers price varies between 20% to 80% but worth looking at this site http://www.gillscruise.com/solo_singles_cruises or contact the number on the page top right and ask one of their cruise specialists. On the theme of singles is there not a friend who you can share with and avoid the issue of these charges. The majority of flights are from Manchester; Heathrow and Gatwick but you can get deals from regional airports. When you book your cruise the flights are part of the deal unless you decide to do your own but then you will also have to organise transport to and from the airport to the ship and back.
Thanks very much for all who have replied to my question.
The cruise is "With Alan Titchmasrh"on the Peter Deilmann Ship MV Mozart on 3rd May 2009.
I think I had better phone direct to get a price for a single cabin.
