how is staying in Honolulu hotel different than in a Waikiki hotel?
Yes, even though technically the entire island of Oahu is zoned as Honolulu, when people say Honolulu they usually mean downtown Honolulu, which is the business district between the airport and Waikiki. Most people stay in Waikiki, and I think there’s only one hotel downtown Honolulu which is the Aston at the Executive Center. If you are visiting the island as a tourist, you’ll want to stay in Waikiki rather than Honolulu. Hope this helps.
