We have driven down and back. We loved it and will drive down again next year.
Coming back we spent 5 dyas in Chiapas, which was incredible.
Lots of check points, but we were always treated with respect.
Everywhere we went people were welcoming and helpful.
Toll roads are in excellent condition and we have driven US, Canadian and Belize roads, of which some were not much better than Mexican roads.
Potable water was available everywhere, food was delicious and hotels were every bit as clean as anywhere else.
