I went with Diana on my first trip to Zim in 1995, have used them a few times since too, and have no complaints whatsoever, except that they aren`t as cheap as booking with the hunters in Africa,
Which technically your not supposed to do, but hey ho, we have to save a buck now and again
One thing I did find out about Diana, they are a very large multinational company, and yet they will still do a deal, last time I used them was in 2002,I was taking a few stalkers that hadn`t been to Africa before,and after I haggled a bit, they did me a very very good deal,not that I`m tight, but I didn`t want first timers spending a fortune and worrying about the £`s whenever they saw an animal.
At that time, they were the cheapest on the market for a 10 day,8 animal hunt.
Now Limpop safaris do the Africa side of things for DIana, the person to speak to is Tina Jepperson,if memory serves me correct.
One thing you do have with Diana, is peace of mind, insurances, any goes tits up you ring them and it`s sorted if poss.
I never used to worry much about anything like insurance etc no to have the payout then
