For years we avoided Acapulco, and finally in the 90's decided to spend enough time there to explore it. We enjoyed ourselves and would/will return, but carefully.
The road from Acapulco to Puerto Escondido isn't boring, but there is minimal coastal exposure, it's a very long drive in one day. There is nothing particularly interesting along the way.
The road from Oaxaca city to the coast is amazing. The one that takes you to Puerto Angel goes through a cloud forest! Coffee plantations, banana plantations, it's gorgeous. It's also very windy and steep. We have done it a number of times and recommend it highly as long as you know that it's not a huge number of miles, but it's a lot of hours.
If you happen to be a plant person, there is a stand of amazing cycads (Dioon holmgreni) right along the side of the road. Details? Contact us.
Again, the road is an adventure worth taking. Just leave really early and plan on arriving for happy hour.
The road south from there goes by Huatulco, which has amazing beaches. Even Salina Cruz is worth seeing, it's a huge port.
It's all good. Even the most boring roads have cool things to see.
