Thanks for the info.
Interestingly - and frustratingly - the cruise docs dont specify the number of formal, informal and casual nights beforehand. We are therefore assuming the nights following days at sea will be formal, the nights in port - casual - and the other nights, where we sail at 6pm - will be informal.
We have a 20kg luggage allowance we have to stick to from SA and that makes a 12 day cruise HARD to pack for. Hopefully we wont stick out like sore thumbsa s they say....
D-day and counting. 14 days to go.
