We will be doing a split stay in Oahu when we visit in April. We start and end our stay at the Embassy suites. We plan on renting a van from Enterprise for our transfer to Aulani for the middle portion of or visit. The lowest car rental rate I've found entails a pick up at N.Nimitz location. They have closer offices but the rates are close to double. I would like to know how difficult it will be to go the Highway location from Embassy suites. Thank you in advance for your help.
