I'm planning a 3 week trip around Spain for my parents (70s). My parents live in Florida and are sensitive to cold weather (under 70 degrees is cold). We have the option of two departure dates.
Option 1) April 14 - May 3
Barcelona (4/14-4/17), Madrid (4/18-4/21), Granada (4/22-4/24), Seville (4/25-4/28), Lisbon (4/29-5/3)
Option 2) May 19 - June 7
Barcelona (5/19-5/22), Madrid (5/23-5/26), Granada (5/27-5/29), Seville (5/30-6/2), Lisbon (6/3-6/7)
I'm concerned the April dates will be cold for Barcelona and Madrid, while the May dates will be hot for Seville. Unfortunately, they have a conflict for other dates in May.
Which would you recommend?
