We are traveling to Guatemala in March with our 15-year old daughters. We want to stay in the Lake Atitlan area for four nights before traveling to Antigua for the rest of our stay. It sounds like Pana may be a bit touristy; where else would you suggest on the lake (both towns and hotels)? Our girls would love a pool but we don't need any fancy. We are interested in hiking, shopping, zip lining and general exploring.
