While I agree with code4 in principal would you know that a 20 000 acre property is fenced or not would fence lines come into play... I doubt it.... I would be weary of generalisation SA as any other country in Africa has great areas to hunt, unfortunately as code4 has indicated there are sausage machine or meat factories... As him I am not a fan of put and take operations, I for one as a hunter would not care if a 60" Kudu was brought in and dropped off for me to be shot just because I indicated that it is a life long dream of mine to hunt one...
In this case I would much rather settle on a 51" bull I hunted on foot on a decent size property. Package deals are usually made up of species that are readily available and that good numbers are present, hence the reduced price, or for outfitters to get feet in their camps during slow months... for example April, May and late September- October.
There are very good packages available but make sure to enquire with regards to flexibility as well as to enquire as to whether you would be charged for species IN THE PACKAGE if they are not harvested or wounded...
Also be sure to enquire even if you are on a package hunt, as to the particulars of such a package, IE.
A breakdown on the daily rate and each trophy fee (in the package) this helps if for instance while you are on safari and move away from the package that you are able to make an educated decision as to whether you would like to trade species or not, and could and will potentially avoid any unexpected surprises come billing time..... (Mostly package rates on days and species are not the same as pricelist rates)
Assumption is the mother of all screw ups...
I am pretty sure though, that no matter which way you go package or A La Carte (if you will), that you'll have an awesome time.......Most outfitters are serious about what they do and look after their patrons very well...
My very best always
