Once you have booked your airfare, you will still need to decide how you are going to get around once your get to your destination. If you're just visiting Oahu and plan on spending most of your time in the Honolulu/Waikiki area, then a shuttle or cab to your hotel and then public transport (THE BUS) will meet your needs. If you plan to get out explore the island you visit there are many ground and air tour companies that will show you everything there is to see, but if you are more independent you may want to rent a car. The best rates for car rentals are available on a weekly basis and rates vary from one company to another, as do the discounts available. Once again, the key is to shop around. Other considerations when renting a car are taxes and insurance, a good idea is to check with your personal automobile insurance company to see if your own insurance coverage will carry over to the rental car.
Inter-island flights between islands are available between each island and take between 20 - 45 minutes. The two main airlines that offer inter-island flights are Go! Airlines and Hawaiian Airlines, advance reservations during holiday and peak periods are recommended. The best fares tend to be available during mid-week travel (Tuesday, Wednesday and Thursday) and discounts are available for reservations made more than 14 days in advance. There are numerous deluxe cruise ships visit Hawaii and NCL are based in Honolulu year round with 7, 10 and 11 day cruises.
