Dale - In the past when we flew into Honolulu we were unable to take the public bus into town because we had luggage which they wouldn’t allow on the bus. Is this still true?

 That still holds true (at least in part). The public bus system will allow you to bring aboard one luggage measuring 24 x 18 x 12 inches. In addition, you are also allowed to bring along carry-on luggage such as a smaller bag.
