What trips may have a kitty and what is it?
On some of our Overland and Basix trips we operate a 'kitty' system for our travellers. The kitty is a cash contribution to a central fund and overseen by the travellers and the crew. It helps fund accommodation, camp meals or activities for the entire group. Contribution to the kitty is compulsory on some trips while voluntary on others - please refer to the specific Trip Notes for details. Kitty amounts published in the brochure may change. Current kitty amounts can be found on our website so please check for the up to date amount 48 hours prior to your trip commencement.
