Between Brazil and Mongolia, we learned about Greece. I had just had the baby, so we didn't do that much. Highlights included watching Percy Jackson and the Lightning Thief (for the Greek mythology aspect) and tasty Greek food from a local restaurant. The adults (my mother-in-law stayed with us for 2 weeks after the baby was born) also watched For Your Eyes Only (it has James Bond being a tourist in Greece) and My Life in Ruins (the actress from My Big Fat Greek Wedding portrays a boring tour guide in Greece who learns to loosen up and finds love).
I was planning to have the girls take a session of swim lessons, but never got around to it while we were on Greece. Maybe when we're studying Zimbabwe...hey, the country may be landlocked, but they still swim sometimes over there!
