Just come back from the 19 Day South West Safari from the Vic Falls (Zambia) to Cape Town. This is a camping tour in an overland truck for 18 - 39 year olds.
I thoroughly recommend this route if you don't have time to do Uganda to Cape Town. We seen so many different landscapes like the jungle in Botswana to the sand dunes in the Namib Desert. I went to Africa with no expectations for what animals I was going to see as I didn't want to be disappointed if I didn't see them... oh boy, was I impressed! We seen over 100 elephants (Botswana has the highest population in Africa), countless Zebra, Giraffe, Hippos, Lion, 7 Rhinos (people who had been on the tour since Kenya hadn't even seen one yet), Buffalo + so much more. The only animal we didn't see was a Leopard, but they are really rare and remember this is the wild, no sighting is guaranteed!
Our driver Sam and tour guide Rachel are both two of the nicest people I've ever met, both from Kenya. They were so informative, like two books of knowledge about everywhere our tour went and the countries we visited. Rachel is a fabulous cook, it was like eating at a fine restaurant every night. They were the best guide's I've ever had, out of all the tours I've been on over the world.
Overall - we are going back to Africa next year to do East Africa and I wouldn't even consider a different tour company to Acacia for a second. The overall efficiency of the company, overland trucks. equipment, meals provided, itinerary and PRICE were all outstanding. I put a lot of research into all the overland companies before booking and Acacia has the best trucks, food reviews and value for money. My boyfriend and I paid something like £1,400 (including the adventure pass) and couldn't actually figure out how Acacia made a profit from that... it really is great value for your money, considering the costs of all the food you eat, accommodation you stay at, cost of running the truck and buying new equipment, wages for your driver and guide and entry fees into all the amazing national parks you visit and activities that are included on the tour.
Acacia also doesn't encourage you or force you to tip anyone along the way like some tour companies do, they didn't even mention the word tip the whole tour. I did a Contiki tour once and after been asked to tip every single local person involved with our tour along the way, at the end he guide gave us all an envelope and said "people usually give me $50, if you don't give me $50 i'll know you think I did a lousy job." - there was none of this pressure from Sam & Rachel (so of course we all gave them a nice big tip at the end because they were so awesome, which they were so humble and grateful for).
Tip - the mattresses provided can get pretty sticky with the humidity. I highly recommend taking a flat bottom single sheet or large sarong to put under your sleeping bag!
Tip - do the sky diving in Swakopmund - best experience ever!
