hi tgif, the coast stretches from main beach in the north to coolangatta in the south and all off these beaches are kiteable at some wind direction.
if you want nightlife and exitement stay at main, surfers or broadbeach and they are still fun places with good restaurants and nightclubs if thats your bag! everywhere south to coolie is more mellow, but at this time of the year when southerlies abound you are best to head to the broadbeach, surfers area, because if the surf becomes unridable then the broadwater with its exotic spots such as kfc and shearwater come into there own!
the coast is fun.

if you want to hang with the locals, go to narrowneck just north of surfers.
