@Krystal92 I think you should decorate in whatever way you like. I know exactly what you're talking about, because I live in a tourist town in Mexico and so much of the decor is so much the same. I actually have been in hundreds of homes here in my work as an uphosterer and I'm so sick of seeing shelves full of dust collecting pottery vases and the walls covered in depictions of geckos and suns and fish and palm trees, with walls painted in gaudy colors ( which is very Mexican).
They aren't all like that, though. One client I worked for had an apartment that you would have thought you were in some trendy place in Manhattan if didn't look out the window- all white and black, lots of stainless steel and super modern. There are actually a lot of modern places here, too.
In both the way I built my house and the way it's decorated, I've used a fusion of traditional materials and building style, with eclectic stuff that suits my taste. And my guests have loved it.
So you might go for something along those lines- keep it tropical in feel, but without all those furnishings you see in every rental where you are.
Some guests might want a place that looks like what they imagine Hawaiian houses should look like, from all the glossy magazine pictures they've seen, but certainly not all guests are going have that image as a deciding factor. And how you decorate can appeal to exactly the kind of guests you'll enjoy dealing with.
And I'd bet there are plenty of repeat vacationers to Hawaii who are sick of all that rattan, too 🙂
