Hi Cate,
Your tour manager is yet to be confirmed, but I may have more information in a couple of weeks if you are interested.
In regards to the optional excursions, reservations for these will be accepted by your Tour Manager and payment should be made in South African Rand only whilst in South Africa. Zambian optional excursions can be paid for in US Dollars or Sterling. Please note these tours will operate subject to minimum numbers and all prices quoted are approximate and subject to change without notice. Your Tour Manager will be happy to provide you with any additional information you may require.
Kindest Regards,
Monty
