if your goal is to kite as much as you can kitebeach is probably your best choice. You do not need to carry around your equipment just start right from the spot.
I personally would not like to live in the center of cabarete because it is too tempting to go out every night and than it's harder to kite the next day
It's also more quiet if you are not directly in the centre. There are lots of places in between the centre and kitebeach and even further. Of course if you are into partying, your way home is shorter if you life in town.
I live in Playa Encuentro about 5 min on a scooter from kitebeach (10 from towncentre) and manage a little hotel called Hooked Cabarete there. Playa Encuentro is the main beach for surfing in the Dominican Republic and when there is wind it is also nice for kiting in the waves there. We work together with Kiteclub on Kitebeach and if you stay with us, you can store your Equipment there and use the compressor for free. As we mainly get kiters and surfers as guests it is easy to meet other like-mined people here. If you are interessted just find us on Google.
Moving around in Cabarete is easy. There are Mototaxis, Minibuses (Guaguas - they just pick up everybody on the side of the road) and normal taxis. You can also rent a Scooter oree a car if you want. I like it the most to move around with my own scooter, because its fast, flexible and economic.
If you have any further questions, regardless wether you are interessted in staying with us, just let me know.
