1st time in Hawaii. Will be in Honolulu 7/25 to 7/28. Then on to the Big Island for 6 days. My question is should we rent a car on Oahu? We are definitely renting one on the Big Island. We are staying at the Waikiki Grand Hotel-renting a condo. The info says they have parking for $17 a day or meter parking at the zoo or free parking around nearby Kapiolani Park. We want to do PCC, Dole Plantation and Pearl Harbor. (Husband is retired Navy). What is cost for taxi or shuttle to & from airport? Any thoughts?
