We hired photographers to jump with us to capture this amazing experience. What we recommend is to review your activity options on our web site and create a list of what interests you and fits into your budget. Review your list to determine which activities do NOT include transportation and rent a car only for those activities. Visitors arriving staying in Waikiki are often surprised to find what a 'big city' it is with tall skyscrapers mixed in among the palm trees and the white sand beaches. Having a car can give you the freedom to explore more remote parts of the island where you can experience the lush tropical side of Hawaii that you see in magazines, TV and in movies.
Most hotels offer parking on premises.
That is not too bad. Keep in mind your Hawaiian vacation is not the best place to pinch pennies, rather invest your time and money wisely getting the most for your money. Some visitors use the bus to get around Oahu. That is NOT a good investment of your time. It is so slow and there is no way to know where you are or what you are looking at when you are traveling.
