A fun thing to do for a party is to hire an old-fashioned jukebox... and I imagine that a fun thing to do during the summer holidays in Cape Town would be to hire a jukebox for a few days. :) I hired one for a party a couple of years ago, and it was a blast - quite literally.
These days the only boxes that you can hire are fitted with hard drives containing hundreds of MP3 tracks. I'd love to find one of these babies that still uses LPs. I guess that finding one, especially in a public place, would be nearly impossible. Please leave a comment if you know of a genuine jukebox that plays genuine LPs. We may just have to visit! :)
