Not at all!
We supply sheets, pillows with pillow cases, duvet and duvet cover (or comforter) for each bed, as well as bath towels. Additional bedding can be collected and additional duvet and cover may be added to your extra hire items at a nominal cost.
In the Safari & Outback 4WDs in Australia we supply sleeping mats and sleeping bags (instead of the duvet), along with the rest of the linen.
