Knowing what to look for does help, so thank you. I'm not sure what I did wrong last night but it certainly was simple this morning. The evening flight is still only 40 Euro per person - try to get from Toronto to Winnipeg for that! Any reason not to book directly on the Spanair site?
Our trip is getting exciting. We reversed the direction of our loop so that we no longer have problems with where our Mondays conflict with open schedules at various places. So we have 3 nights in Madrid, 2 in Toledo, 3 in Seville (including a Cordoba day trip, 3 nights in the 'pueblos blanca' then 5 nights in Barcelona (including Figueres and Sitges).
Just have to figure out those four nights with a car in the south and we're ready to fly!
Thank you very much for all of your help; it feels like we have a personal concierge who really knows the terrain.
