JMHO...I would simply request a high floor. And if
you don't like late evening noise, I suggest that you request a room on the marina side.
There is noise within the Hilton Hawaiian Village due to various events/live entertainment. The level of noise will range based on the location of the event/live entertainment compared to each of the towers. The Lagoon Tower is the oldest tower compared to the other two HGVC towers at HHV. The Grand Waikikian tower and Kalia towers were newly built and offer better sound proofing. Lagoon Tower is an old converted apartment building therefore it doesn't have the latest and greatest (for example: slow elevators, small bathrooms with tub/shower combo, no in room washer/dryer).
