I am planning a trip to Chiapas in Jan 05. I plan to fly into Tuxtla Gutierrez, rent a car, then drive directly into San Cristobal. From there, I plan to take around 10-12 days driving around as much of Chiapas as possible, definitely including the ruin sites, the falls, Laguna Miramar, etc. I am a 33 year-old female travelling alone. Any concerns for travelling alone? As well, any advice about how to go about all this would be appreciated.
