The pictures on the Rovos Rail web site show people VERY dressed up, but those people can't have been about to go on safari! There will probably be an option to store luggage since you can't take much on the small plane that flies to Singita, so some may decide to dress up.

We will have at least half of the train so nobody will look out of place in their ASC or CCC attire.

For those of you branching off into more research - so much fun - the fodors message board is a treasure trove of information. Especially look for posts by "safarinut".
