We cleverly organized our trip to give us the longest possible layover in Paris.
Although the day was quite hot and we were a bit strung out from our trans-Atlantic flight, we enjoyed the quick visit.
But we almost didn't make it back to the De Gaulle airport for our flight to Frankfurt. If we'd chosen the local instead of the express train (we couldn't figure out the signage) we would have missed it! But the travel gods were kind and we made it just in time.
