Consider staying at a "Green" hotel on your next vacation to Hawaii or anywhere else in the world.
Whether it's a weekend getaway or a week-long stay, make sure your hotel has the same green habits as you do at home. Since hotels are such large consumers of resources--the hospitality industry spends $3.7 billion a year on energy and typical hotels use 218 gallons of water per day per occupied room--it is especially important to support environmentally conscious businesses whenever possible.
The Green Guide to Finding a Green Hotel list several sites which offer searchable eco international directories based on different certification programs for the travel and tourism industry.
If the Hawaii hotel or any hotel you want to stay at is not listed in any of these directories, you can ask them directly about how they handle different environmental issues such as how do they handle their trash and recyclables.
If more hotel guests let their hotels know that being green was important to them, I am sure that more hotels would make a greater effort to be environmentally friendly in their practices.
