As a sometimes contributor of advice to this forum, I'd like to change roles and ask for a recommendation.
My wife and I have been to Kauai many times but have never visited any other Hawaiian island. We are heading to Kauai in August and have decided to visit another island for 3 or 4 days on our way to Paradise.
We are all about beaches and gardens. We like a good hike as long as it's not too steep, and as former restaurateurs we do dig good food in comfortable spaces. We aren't big on what might be called conventional tourism; for instance, we have no interest in Pearl Harbor. However, we love Hawaiian culture and history.
So . . . . Which other island do you recommend for a visit? Should we do the volcanoes and lava flows on the BI? Snorkel on Maui? Experience Waikiki? None of the above?
