I'm listing Port Canaveral (our home port) since I can't find Santo Tomas Guatemala. It was chilly, cloudy and a little rainy. There is very little to do in port and in the neighboring town. We decided to take a water tour of the river and into Livingston. Cost was $49 per adult. It was a decent tour. We were in a power boat for about 45 minutes before we saw anything. Stopped at the hot springs for about 15 minutes, saw some mayan villages, and then went to Livingston, which wasn't really worth the trip. It was not a built up port town which was somewhat refreshing, but there was very little to do. Our kids played at the playground near port and had fun doing that. Then we took the 45 minute boat ride back.
