Thanks for you genuine concerns. A document is currently being prepared and should be shared with all participants by the weekend.
It will contain all that you are asking for, however just to clear the air, there will be a shuttle to convey all participants from the airport to the hotel of stay. You arrival dates have been shared to allow the shuttle driver know when to come to the airport. Also there will be some team members to direct you to the bus, just look around for an individual(s) holding a card with the inscription Wiki Indaba 17.
Hope this helps....
