I've been over most of north america and Hawaii.... I wouldn't move to Hawaii as One could see most things in a weekend and then it gets repeated, and it's a long way and expensive for a weekend mainland trip.
I would have recommended San Diego, but if she's to stubborn for that, well good luck. The only other place that's warm and has surfing and an island is Vancouver Island in BC.
Don't sweat the petty things; Pet the sweaty things !!!
