Don't have a fix plan, I haven't even booked yet, just announced my absence at work.
But I know people in Ciudad de Meeeehicooo, will be there the first week at least and then dunno yet. Maybe also visit someone I met some years ago in Ecuador who lives in Aguascalientes. Visiting the costa, maybe Oaxaca/Puerto Escondido, maybe Baja California sur, really don't know yet.
You got recommandations (this reminds me of sending PI some tips for switzerland

)?
