The life of a tourist is heaven, and when you're planning a trip to Hawaii, you are in for the experience of a lifetime.
To fully ensure that you soak in all the cultural richness which this state of America has to offer, you should try to learn as much of the language as possible, and spend at least a month on vocabulary learning.
This book will help with that. Whether you are a new student of the Hawaiian language, or an intermediate or advanced learner, you will be able to absorb and retain hundreds to thousands of new words, and make sure that your vacation in paradise is also an informed and sensitive one.
