I guess there are all kinds of boring tactical reasons that you can read about here. Personally, I've been a big fan of Spain going way back, at least to 2008. But wait, there's more.
First of all, I don't have anything against Holland or the Netherlands or whatever they're calling themself this week. I think the song "Holland 1945" by Neutral Milk Hotel is just gorgeous and perfect. (O/T but wasn't Neutral Milk Hotel supposed to get back together or something? What happened with that?) By all accounts, Holland is a beautiful and wonderful country and all that jazz.
But Spain! If I had to pick one of the two countries to live in, I think I'd have to pick Spain. First of all, which sounds better to you:
"Spain 's location on the temperate zone lends it a sub-tropical climate almost uniformly throughout the year."
"The Netherlands has a maritime climate, with cool summers and mild winters."
Cool summers and mild winters I can get right here! Give me some of that sub-tropical climate almost uniformly throughout the year, brother!
Plus, I like tapas. What's Dutch food? Hutspot? "A dish of boiled and mashed potatoes, carrots and onions"? No thanks. I'll take some tortilla espanola and Jamón ibérico any day. And Albariño! I love Albariño. Do they even make wine in Holland? I can't be for anyone who doesn't make wine.
So yeah, Spain.
