We rented two surf boards from Kina Surf shop and the staff/owners could not have been more helpful. They had a good assortment of boards to rent from beginners to more advanced surfers. Their stock of rentals made it easy to find a board for me that was similar to mine at home but good for the conditions. They also had a great selection of boards for my daughter to use.
The staff was also very good at pointing out the different breaks and times to go and how to avoid the crowds.
In one of the heavier breaks, the leash broke and the shop was great at replacing without any issues. I was in and out of the store within minutes.
The store has everything - which made it great to just buy our suntan lotions there then trying to bring it down from the US (TSA issues). Good selection of board shorts, rash guards and bathing suits.
