Sorry, just noticed this now.
Spain was incredible. Loved it... loved the food, the warm weather, the architecture and history, the women (many times during the trip I wished I was still single), loved it all.
Visited Barcelona, Madrid, Cordoba, Sevilla, Granada and Benidorm.
With the exception of Barcelona, I was surprised at how small all these cities were... you can literally walk across most of them in 30-45 minutes.
Favourite City: Liked them all, but probably Sevilla. Absolutely charming, gorgeous city. I understand why they call it the heart of Spain now.
Highlight of the Trip: Watched a FC Barcelona game at Camp Nou (was fortunate they were playing at home that weekend). Neymar scored 2 goals and they won 2-0. The atmosphere is UNREAL. over 100,000 rabid fans. Total opposite of what you would see at the Air Canada Centre for a leafs game.
Most Impressive Attraction: The Mezquita in Cordoba. I've seen a shit ton of cathedrals in my life, but the inside of this one was just incredible. Sagrada Familia was a close second.
Best Food: Seafood Paella along the beach of Barcelona of course! Although all the tappas were very delicious.
Thanks to everyone who provided suggestions.
