Driving from Texas to Zihuatanejo

We plan on driving to Zihuatanejo in September, and would really appreciate any information you might have such driving routes, hotels, ect.. Any info would be greatly appreciated. Currently, we are thinking about crossing into Mexico from McAllen to avoid the long delays in Laredo. Thank you in advance.

In addition, I did a search in the archives, but I could not locate any current postings.

We've crossed at Eagle Pass/Piedras Negras, as well as Brownsville/Matamoros.
We were warned away from a couple of the other crossings in the general Brownsville area, but sorry, can't recall now which ones. With a few exceptions, I think every one of the US/Mexico border crossings is "the wild west" - the sooner one gets away from either border, the better.
