After three months and $5 million of extensive renovations, the Sheraton Waikiki Hotel has unveiled new convention center facilities.

Hotel officials said the nearly $200 million plan to enhance the Sheraton Waikiki includes Waikiki's largest hotel ballroom area, the Hawaii Ballroom.

The new function space was unveiled at the 1,100-person attendee International Women's Leadership Conference, which was hosted by Gov. Linda Lingle.

Physical improvements to the 45,000 square-foot indoor meeting facility stretch from the foyer area and the 26,000 square-foot Hawaii Ballroom to the 14 smaller conference rooms, which were completely redesigned by local architect Terry Hendrickson.

The transformation of Sheraton Waikiki's convention facilities is part of a nearly $200 million hotel-wide upgrade plan to modernize its facilities to reaffirm its place as the international conference center of the Pacific.

Kyo-ya Hotels & Resorts, LP owns the two Sheraton Hotels in Waikiki, The Royal Hawaiian and the Moana Surfrider, A Westin Resort as well as the Sheraton Maui in Kaanapali, Maui. Kyo-ya Hotels & Resorts, LP is one of Hawai'i's largest employers, with nearly 3,000 workers.

The hotels are a part of the 12-hotel group of Starwood-managed properties in Hawaii.
