Hi Dr. Jacki,
Thanks for your question. There are options...if you are limited to a week's vacation, a seven-day cruise aboard Norwegian Cruise Line's "Pride of America" is a good choice to sample the islands. Since all of your meals and your accommodations are included aboard ship, it can be more economical than a land-based vacation, and you will see the highlights of the most touristed islands. In my humble opinion, though, the best way to see the Hawaiian Islands is to take a land-based trip. You can see two islands in a week, or, if you have more time, add another island to your itinerary. My personal favorites are Kauai, the Big Island, and Maui. Each island has a different "personality", so check with your local knowledgeable travel agent so they can "qualify" your needs and interests to point you in the right direction. Also, they can shop their reputable suppliers for the best deals for you. Good luck!
