There is the Hilton Hawaiian Village and Hilton Waikiki in Waikiki. They are far apart, so make sure you know which one you are going.

If you only have carry on, taking Bus 19 is fine, it goes to both Hiltons. Late night will probably take you 45 minutes to the Hilton.

All buses have audio announcement and most buses have displays indicating next stops.

Be aware, Hilton Hawaiian Village is doing a lot of constructions on Kalia Road. The bus stop in front of Hilton is cancelled. Recommend getting off a stop prior, in front of Ilikai Hotel.

You can check real time bus arrivals at http://hea.thebus.org/nextbus.asp?s=913 if you are leaving HNL.

Circle Island bus routes 52 and 55 are no longer the same bus, they meet up on Haleiwa town.
