I've read all the recommendations on the Teotihuacan tours and they don't look great. I don't like shopping and I don't want to be shuttled into a gift store, HOWEVER I'm a solo traveller and I don't speak Spanish and I can't afford $150 for a private guide.
Given my situation I am going to be stuck taking a tourist tour. Can anyone recommend any, Wayak, grayline, viator, etc??
