Getting around
A practical guide to getting around Lake Atitlan by boat warns not to plan around a strict schedule: the public lanchas connecting the lakeside villages are cheap and frequent but typically depart once they've filled up rather than at a fixed time, so build in buffer if you have a connection to make. Their firm advice for a day trip to another village: always confirm the last boat time back before you settle in, since missing it means an unplanned overnight, and pack layers since mornings and evenings on the lake run noticeably cooler than midday.
