My wife and I are taking our 4 children (14, 12, 10, 5) to Europe for their first trip from 4/1-4/15. Our original itinerary was:
4/1-4/7 in Paris
4/7-4/10 in Provence
4/10-4/15 in Italy
The Italy portion of our trip is now cancelled due to COVID-19. Instead of flying to Rome on 4/10, we're considering a 4 hour train ride from Marseille to Barcelona on the morning of 4/10. We would then change our flight (Delta + SkyTeam) to fly out of Spain somewhere on 4/15. Given our children's ages, what do you recommend that we do in Spain from 4/10-15? Aside from taking the to Sagrada Familia, I'm wide open. Do we spend the whole time in Barcelona? Split the time and head to Madrid? Elsewhere in Spain?
Thank you for any guidance you can offer. For the record, we're still considering whether or not to even go on the trip due to the virus. Rather than get into that topic here, please just assume that we're going and will have a few days in Spain. Help us figure out what a fun few days in Spain might look like! :)
