Could someone summarize the differences between the different villages around Lake Atitlan? We will be staying at Panajachal for 2 nights and would like to visit 1 or 2 of the villages. Our preference would be to see the least touristy of the villages. A friend said that when she went to the large village (Santiago Atitlan?) the people were very aggressive about trying to sell her things. Is that typical for most of the villages?
