Hello Fellow Cruisers!!

My wife and I have booked a Hawaiian cruise and would be very appreciative if some of you folks who have been there would be kind enough to fill us in on the do's and don'ts.  Our cruise is with another cruise line because Carnival does not offer a seven day cruise. We will be embarking in Honolulu on a seven day cruise that winds up back in Honolulu. Since we made flight arrangements ourselves, we plan on arriving in Honolulu a day early and spending the first night in a hotel on Waikiki beach.
