Safari SA for singles

Hi
I might be going to SA for 10 days at the very beginning of November and am a solo traveler.
Wouldn't mind joining a group of happy and fun people ...doing a safari...
Have checked a bit the threads but came not really across many infos for safari for singles...
Anybody as some advice?
I found an offer on the web from safari for singles (4 days trip): has anybody done it? can u reccomend this or other tours?
Last but not least:
- Kruger a must?
- Shall I rent a car and drive down to CT instead of staying aroung Jburg for my other 6 days?
Read that it's a beautiful drive...(maybe one way car oneway flying?)

Thanks for all inputs

For starters, Cape Town is a much nicer, cleaner, cheaper and friendlier city than Jo'burg. Not just my opinion, but the words of many.
Kruger is one of the best in the world, but if it's out of your way then there is plenty going on in other parks without having to pay the crazy Kruger prices.
The drive from Jo'burg to CT is very nice and there are numerous parks on the way not far off the main route, that you can do.
A four day safari trip? I don't think it's necessary. I've done several 1 day safaris and from 10 in the morning till 8pm was enough for all of us. A two day trip with one night camping will suffice. The chances of seeing certain species doesn't really depend on anything but good luck. You can go on a month's trip and see little, then again it's possible to see a cheetah in the first 10 minutes of the adventure.
Don't avoid Jo'burg altogether, but if you've the opportunity to spend the time travelling to CT and staying there for a longer period, that would be my choice, hands down.

We took a GAP tour last November (Kruger and Kingdoms, I believe it was called, although the itinerary looks a little different this year) and absolutely loved it. It had a few days of safari, plus beaches, lagoons, some sightseeing in cities, and a lot more. There were 3 couples and the rest were solo--for a total of 13. I highly recommend looking into something like that. We shared our honeymoon with some really great people and saw some amazing things!
