Hi all,

My itinerary for Spain is looking like this:
Madrid May 18-22
Seville 23-26
Barcelona the rest of the time till June 1st

Does anyone have any suggestions on places that I should ABSOLUTELY see while I'm there and are there any other places that I should go to?
I was thinking of going to some island/beach before Barcelona but have been looking at flights which are all expense...
Does anyone have any suggestions?
Thanks in advance,
Irina
