As a kiting holiday destination Cape Town, South Africa has to be high up on the list of choices. December is kiting season in Cape Town, with beautiful warm weather and wind all day everyday. There are tons of beaches to choose from depending on your skill level. Langebaan is flat as a pancake for fun or freeride. Muizenberg has warm water and small waves so its great for working on your technique or getting your tricks locked down. If you're feeling confident you can even try Kite Beach or Big Bay (Where the Red Bull King of the Air was held in 2013 and will be held again in 2014 http://capetown-watersports.com/red-bull-king-air-2014/
) On top of all that, the South African currency is weak, so you can get gear, go out to eat, or explore the city while not spending a fortune. Check this out for more info http://capetown-watersports.com/
I was in Langabaan in Jan, great kiting nothing else to do, spent a couple of days in CT after and really didnt like the city at all! Not very safe either and I really dont want to have to worry about being robbed for a 10 min walk from a bar to my hotel!
