You don't have to. Plenty waves closer to Huatulco. 7 trips now and not once did I surf Barra. Stay at a hotel in Huatulco and hire my guide. Empty early. Surf one spot he has access to and its rare for anyone else to be there. And if they do show up, its late morning. Control your trip. Go when you want. Leave when you want. If your significant other is a non surfer, let her sleep in and you sneak out for a morning session and come back for breakfast and drinking by the pool.
