We are in the process of assembling our clothes for an arrival at Exeter River Lodge mid-October. Layering is the order of the day we have been told, but should we include fleece outerwear? If so, full jackets or just vests? We will be including waterproof windbreakers that certainly provide warmth also. Because our travels will be continuing on from Sabi Sand, we would prefer not to bring fleece garments if not necessary, as we will have no additional needs for them. Also, we intend to purchase "bug spray" in Joburg in lieu of packing -- assuming a good selection. Right? TIA for any advice offered.
