Although Guatemala city is usually not the greatest place to be when you are traveling as a tourist, there are some activities that can be entertaining during you stay here. One of them is Xpark (http://www.xpark.net/), located inside Guatemala City has some things to do, as long as you don’t weight more than 180 pounds (around 80 Kg), and that is not too many people. It has some extreme sports activities for the casual adventurer, a real extreme sports aficionado would hardly find them very entertaining.
Pizza is good, and it has a nice skating ring.
