According to accommodation website Wotif, 13 places, including hotels, motels, lodges and holiday parks, were fully booked for tonight. Fifteen places were booked for Thursday night apart from Breakers Boutique, which was charging $335 for a night, and three hostels.
West Coast Motel Association president Bryan Williamson, who runs the Bella Vista motel in Greymouth, said demand for accommodation had been "humongous" since the Pike River coal mine tragedy.
"We're absolutely shattered but we've just got to keep moving," he told NZPA.
He said some people had been directly affected by the mine tragedy but were still running their hotels or motels.
His 18-unit motel was booked out for tonight and tomorrow due to the national remembrance day, which will be held at the Omoto Racecourse on the outskirts of Greymouth.
However, he said Greymouth was a popular destination for tourists due to the TransAlpine train trip and Punakaiki's pancake rocks, so accommodation was often fully booked.
Aachen Place Motel's Brent Foster said he was also booked out for tonight and tomorrow.
Most places in Greymouth were "well and truly" booked out for the next two nights, with some people forced to look for accommodation in Hokitika and Punakaiki, he said.
A range of groups had been staying at the motel including police, fire service, Red Cross and St John representatives.
Meanwhile KiwiRail, with the Rail and Maritime Transport Union, will be running a special passenger service to Greymouth tomorrow for the service.
"There are close historical ties between the mining and rail industries and we doing this as an expression of our deep sympathy and support for family, friends and colleagues of the lost miners," KiwiRail chief executive Jim Quinn said.
The service, which would leave Christchurch at 8.15am, would raise funds for the Pike River Miners' Relief Fund, he said.
Passengers would be able to disembark and re-board the service at Omoto Racecourse so no additional travel arrangements would be necessary, he added.
Air New Zealand has also added a direct service, from Auckland to Hokitika, so more could attend the tribute to the 29 men.
This week local volunteers and contractors have been busy preparing the racecourse, which looks out to the Paparoa mountain ranges, for the remembrance service.
The racecourse's grandstand, seating 1000, will be filled with the families of the 29 men and Pike River staff and their families, while two other grandstands have been brought in and one more is on its way to seat some of the 7000 people expected to attend.
A stage, which will seat 18 people, and 29 tables to represent each of the men, will also be set up and each table will have a miner's helmet and the name of the person who died, along with various symbols including small stones and pieces of fern.
