I've seen mentions that some hotels sponsor a free walking tour, but can't find any actual details on it. Does one exist?
Ideally I'd like to see the old buildings - the palace and so on, but even an informative tour around the beaches - Waikiki etc, maybe Diamond head, would be fantastic.
Well as they say: "There is an app for that". There is apparently an application for iOS that can provide you with self-guided tour of Honolulu.
There is also another self-guided walking tour of downtown Honolulu.
All of the guided tours of Honolulu would actually require people to pay but it may be possible that the hotels would offer discounts or even pick up the tab for that but this would have to be investigated locally when you check in.
As far as Waikiki is concerned Frommer's gives a few but with no indication if someone will guide you through the tour.
