A sale to promote travel to Hawaii is on.

Numerous travel packages to Hawaii are on sale as part of a $4.5 million marketing campaign through the Hawaii Visitors and Convention Bureau to boost visitor numbers to the state.

Among the deals under the new theme of “;Discover more of Hawaii for less than you imagined”; are: Anywhere from 35 percent to 50 percent off hotel stays booked through Orbitz and Expedia, a $500 air credit, free breakfasts, a free rental car, even a $50 grocery certificate.

The campaign is part of an additional $12.5 million pumped into the state's flailing tourism industry since May.

Visitor numbers were weak throughout the summer, driven home by a 17.4 percent plummet recorded in August. Hawaii hotel room occupancy in August also dropped to 74.4 percent, the same 10-year low set in August 1998.

The state's tourism marketing arm and wholesalers hope the concerted effort will bring results during turbulent times in the economy.

“;These packages are good news for travelers who may have been deferring a Hawaii vacation over cost concerns,”; said John Monahan, HVCB president and CEO. “;The savings being offered mean the cost of a Hawaii vacation can now be less than a year ago.”;

The deals are listed at GoHawaii.com/Value, with some available through the first quarter of 2009.

Pleasant Holidays is offering savings of up to $500 a couple on a Hawaii vacation, plus half off a companion's airfare for visitors flying from Los Angeles and San Francisco. Rates for three-night hotel stays on Oahu and Maui begin at $565.

Many hotels, including the Westin Maui Resort & Spa, Sheraton Kauai, and Waikiki Beach Marriott, are offering daily breakfast for two as part of packages sold through Northwest Airlines' WorldVacations.

Outrigger Hotel & Resorts is offering $50 and $100 Foodland grocery certificates for those who book a five-night-stay at any of its condo properties on Maui.

More airlift to the islands is also available.

Delta Air Lines added more flights from Los Angeles to Kauai and the Big Island, and from Atlanta to Honolulu earlier this month.

Alaska Airlines is adding seasonal flights twice a week from Anchorage to Maui from Oct. 31 to April 25, and will commence year-round once-a-day service between Seattle and Kona beginning Nov. 17.

“;Hawaii is more affordable and accessible - and as enchanting as ever,”; said Monahan. “;Hawaii during the winter is spectacular with the balmy weather, exciting outdoor activities and a spirit of cultural diversity found nowhere else in the world.”;
