I will be visiting Hawaii for 16 days. 7 in Ewa Beach area and another 9 in Maui. I am renting a home from a couple that live there and have been corresponding with them. Would like to bring a couple of small gifts from Canada as a thankyou. Can anyone let me know what types of things are difficult to purchase and would be nice as gifts? Not sure if bath and body would be nice or if some different food items?
