Speaking of two year olds throwing coins, our last trip we were on the boat with a couple who child was getting tired and started a mini melt down, the dd tossed one penny in the water and like magic the baby laughed so hard that it made us roll laughing, the dd gave the baby pennies to toss and lets just say he had us busting a gut, it was really so cute, something so simple made him so happy, he didn't want to get off the boat. Stupid things like that are really priceless.
