During our recent trip to Athens, we stopped by the National Archaeological Museum of Athens (en.wikipedia.org/wiki/National_Archaeological_Museum_of_Athens). Now, no offense to any history buffs out there, but 2 hours in a place like this is no fun for a 5-year old. The only really exciting part of it for him was watching his dad have a heart attack every time he tried to touch any of the ancient pots sitting on their pedestals. Fortunately we found a semi-decent spot inside where he could be a kid.
