I paid $600 to feel rushed and we didn't get to see everything we wanted to. The driver was very knowledgeable of the Oahu island, which we appreciated very much. My advice is to just do a little research, talk to a couple locals and rent a car.
We saw so many amazing things! Nicole was our tour guide/driver. We had six in our group with a variety of interests. She was able to take us to the points of interest we had on our list and more. We saw two lighthouses-Diamond Head and Makapu'u, Diamond Head Lookout, Makapu'u Lookout, Byodo-in Temple, Chinaman's Hat, Halona Blowhole, Hanama Bay Nature Preserve, Dole Plantation, Kualoa Park and Turtle Bay. We had lunch at Ted's great inexpensive lunch and dessert-pineapple cheesecake with macadamia nut crust -yum. Also the Dole Plantation has pineapple soft ice cream. Nicole was great and I can't say enough about how wonderful our day was. Thanks!!
