Hi Annabella
Yes, we only have one date - 26 March.
You would need South African Rand for South Africa and Namibia, CFA Francs for Senegal (you will probably be able to get these on the ship, or maybe use US dollars) and euros for all the other destinations.
I can't find any information about the ship's sockets on the cruise line's website but you could get a universal adaptor which will be suitable for any situation. You can also use it for future holidays, wherever you go.
Kind regards
Olly, your editor
