Never been to Spain...or Jamaica...whatever. But, I have been to the North Shore. I totally enjoyed Hawaii. Great weather, loved the ocean, snorkeling. Wife has been multiple times, and she absolutely loves it.
I'm not sure how serious she is... but the wife says she wants us to move to Hawaii. She's a beach girl. Our son is in the 6th grade. Once he done with HS, she tells me she wants to move there...buy a little place on the beach. I think she's serious. I'm indifferent. I'm fine where I am... nice community, etc.; but I"m not necessarily opposed either.
Hawaii is definitely a different culturely. I couldn't imagine myself there in a million years growing up.
