HONOLULU, Hawaii -- More than 100 people filed through the Turtle Bay Resort Saturday to protest Kuilima's planned expansion of thousands of new hotel rooms.

Protesters said the proposed hotel rooms would desecrate Hawaiian burial grounds. Kuilima responded, saying it was committed to protecting all Hawaiian cultural areas.

Kuilima got its permits 20 years ago, approving plans to build up to four hotels on either side of the current Turtle Bay -- a total of 3,500 additional units.

Protesters said they worried ancient Hawaiian bones will be dug up.

"My concern is they are going to be constructing their hotel development on a burial site. Those sand dunes are known burials," said Vicky Holt Takamine, of the 'Ilio Coalition.

North Shore community activists also worried about the planned development's impact on traffic and housing on top of the burial ground concerns.

"No matter which way we look, there are community concerns. It really, really should be addressed before they proceed," said Gil Riviere of the Keep the North Shore Country group.

Kuilima made no comment Saturday, but hotel workers offered protesters iced water and cool towels.

According to a written Kuilima statement, the hotel company has already received approval from the state for a comprehensive archaeological study of the area. The statement also said that Kuilima was fully committed to carefully monitor the construction area at all times.

Kuilima said it would take immediate action with experts should any burials be found. It also said it is guaranteeing 100 foot shoreline setbacks, and in sensitive areas, like Kawela Bay, 300 foot setbacks.
