We really enjoyed our trip to Chobe from Victoria Falls, which was organised personally by Webster. The tour, which was very reasonably priced, was extremely well done, and a great value for money. We had a whole safari vehicle to ourselves and a great guide from Tony Mobile, who really knew his stuff. We checked with some acquaintances who went on similar tours, and found that they saw much less, were packed into vehicles with many other tourists, and we suspect they paid around the same price as us. Very pleased with our entire experience, and highly recommend that you skip checking out other tour agencies and stick with DK Tours.
For reference, we also chose to go with them for our airport transfers, as they were cheaper than our own hotel.
