We are signed up for a cruise next week that goes to several stops and stays the whole day or even two--Maui (kahului), Kaui (Nawiliwili), Hilo and Kona. Can anyone advise us about where would be interesting natural sights we could visit in a day? We are active middle agers, but not adventure travellers per se. We like snorkeling, walking, history, and wildlife. On any recommendation, can you also suggest an inexpensive way to get there and the approx costs? (ie. busses, local taxi). We don't want to do the cruiseline-based tours. Thanks!

Also we are getting from LAX to HNL on United in Y. Can anyone advise about the for-purchase meal on this flight? Would we be better off buying something in LA and packing it along? Anything else we should know about?

Thanks!
