Around that area you might be hard pushed meeting Spanish…. its a very highly ex pat populated area….. a bit like the UK with sun really. Do yourself a favour and do travel around, there is so much more to the Costa Blanca ( at the risk of upsetting anyone who lives in that area).
I’d second the avoid the bar experts bits as well…. we got ‘valuable help’ off one idiot in a bar once, and it was all total tosh! You’ll find a lot of people are only too happy to help, but perhaps not with your interests in mind. But one idea is to find places that offer live music, so you get good entertainment in to the bargain.
