Donna, we always enjoy outdoorsy trips, but we also like cities a lot.

For the outdoors fan Table Mountain is a real highlight, you could go independently and spend more time walking/hiking some of the trails. We were rained out the day we were supposed to stop there, but the Kirstenbosch gardens looked like they would be great and as Pam says Cape Point and the wine tour are out of the city. Cape Town isn't a congested city - at least that wasn't my impression - and it has quite a lot of interesting museums and history to learn about and enjoy and is very walkable in the city center.
