Your choices are quite interesting, especially that you chose things you like instead of picking up a survival book or movie to make your time on the island a little easier. Guerra Mundial Z can be read again and again in a month, and Blue seems to be a good choice for relaxation. But I like your drawing idea the most, because capturing the beautiful scenery of the island in your drawings can be a really good memory and you will have your own gallery of the whole trip when you come back.
