Honestly pretty much anything is within an hour and a half drive in Oahu. It’s a pretty small island! My husband and I stayed at Aulani for a 10 day trip but still did plenty of exploring (including going to waikiki to walk around and dine). We personally didn’t find driving to get to Waikiki or anywhere else a big problem and LOVED Aulani. It’s a beautiful resort and we are so looking forward to going back some day soon!
