Bus from Zihua to Puerto Escondido

Hola,
Is there a bus that leaves from Zihua and goes to Puerto Escondido, but I would avoid transferring buses in Acapulco? It would be for sometime around Wednesday December 17 or Thursday 12/18.
Thank You

I seriously doubt any bus passing through Acapulco is not going to stop there since a direct bus from Zihuatanejo to Puerto Escondido really doesn't make sense for any busline due to such low demand and frankly doesn't seem like a realistic expectation. Transfers really are no big deal. I wouldn't let that be an obstacle to my travels. Often if you're industrious and check other buslines in the terminal or with Estrella de Oro (they have their own terminals) you can find a different luxury class busline leaving sooner than if you stick with the same busline.
