When visiting Hawaii anyone wants to see and do a lot! There are usually 2 obstacles to that- time and money! It is only that much that you can see on your vacation to Hawaii as it is limited in time.
I think a great solution to that dilemma, is a Go Oahu Card. If you are going to spend some time on Oahu, it is worth it to buy Go Oahu card, as it will provide both savings and will push you to see and do as much things as possible in 3, 5, or 7 days.
Go Oahu card essentially is a pass to 36 activities and places in Oahu,Hawaii. You can do as many things out of the included one a day as you want, actually as many as you can due to the working hours of the places. 3,5 and 7 days Oahu passes have the additional bonus activity like Kaulua Ranch Half-Day sunset experience or Ha-Breath of Life diner show at Polynesian cultural center.
