Where:vacation+dinghy course in January?

Dear all,

my girlfriend and me are looking for a place where we can have a nice
vacation and learn/improve on sailing a dinghy.

We are completely new to sailing, and are currently having our first sailing
course this week, but we already love it. It' s an intensive course (5
lessons a 5 hours in a week on a standard Laser). Now there is the idea of
taking a follow-up course during our next vacation, which will be in
January. (We live in the northern hemisphere, and would like to get a
break from winter this year).

So far the idea was to go for a nice and long 3 week vacation with 1 week
of sailing. Potential targets so far were South Africa, New Zealand, and
Australia. Searching the net, I found little information on hotels or holiday apartments with nearby sailing schools that teach you to sail something
the sort of a standard Laser. What are good places or where should I
look?

many thanks in advance,
Andreas
