Travel plans went blooey on us

We got into Washington Dulles half an hour early and things were right on track. Then we went past the boarding time of our Aer Lingus flight to Madrid and they finally announced the plane was broken down and they had to wait for a part to be flown in from Philadelphia. We finally got off the ground and 9 pm, 3.5 hours late. We made good time on the flight, but our connecting flight to Porto was 3.5 hours after our original scheduled arrival, so by the time we got through customs and baggage, it was 10 minutes later that our Porto flight. Rebooking by air would have been ridiculously expensive, so we decided to take the overnight bus from Madrid to Porto. That will keep us on track timewise, but we will be pretty tired and not much sightseeing time in Porto. However, we did go to the Prado museum in Madrid this afternoon. Right now, we´ll take it easy till our bus ride west later tonight.
