@Walter Hinteler,
I took bus tours three times in my life.
To see wildflowers in california; I got nauseated (back of bus) and highly irritated. That was the last time.
To go to Chichicastenango in Guatemala. Worth it. I suppose the market a cultural mixed bag, re tourists, plus there were goosestepping soldiers that year, which I then didn't comprehend.
A trip to Tenochtitlan (sp) near Mexico City, the bus not my idea. Well, it wasn't for Chichi either, but I couldn't have gotten up there by myself.
You can put me down for anti tour.
