I'm going to Spain in late June, will be visiting Valencia, Madrid, Zaragoza, Barcelona over 2 weeks. Does anyone have experience or advice on pickup in these cities? I've heard Spanish chicks are some of the hardest in Europe, there's a deep stigma attached to promiscuity which is particularly strongly associated with prostitution. Can anyone confirm/refute this?

Yup, very true.. I live in Spain and we have had countless discussions about why that huge gap exists with Spanish girls... Recurrent explanations : religion, central role of family in all Spaniards lifes (live at or within 1km of their parents LOL until 40yo+..).

If you are in Spain for a short time I would advise not to waste too much time on them and go for the low hanging fruits of tourists... (yeah pity I know cos avg Spanisg girl is pretty hot..). Now, they do get a bit easier on holidays, at the beach... (Zaragoza?? drop it for girls...)

PD: "I've heard Spanish chicks are some of the hardest in Europe" where did you hear that? out of curiosity. I would tend to confirm, although Italians may not be too far away.
