It really does depend upon your skills level and sight reading ability. If you want to accompany, there may not always be time to have an advance look at the piano part. You could play in Care Homes, where I have quite frankly encountered some very low standard pianists who get away with it because no one expects much in the first place.

Kauai, which gets more rain than any of the other Hawaiian islands, also is the most lush. Finding a lush, secluded beach on Kauai isn't too difficult -- if you're willing to work for it. Most of Kauai's secluded beaches require a hike, a drive down an unpaved road, or, in one case, a boat ride. Some beaches are bounded by lush cliffs, others are dotted with palm trees.
