Based on a projection by the London-based CWC 2007 venue development management company, Sinclair, Knight and Merz (SKM), Singh said a total of 37,000 people will visit Guyana next March and April.
With at least 15,000 people expected in the South American country at any given time for the second round Super Eight matches, Singh suggested that churches and other organisations set up tents with cots and bathroom facilities to supplement the 2,500 expected hotel rooms and 3,000 bed and breakfast rooms.
"It's a huge challenge for us and we don't want to see it as an obstacle, we don't want to see it as a constraint but we want to see it as a challenge," Singh told AFP.
He also encouraged businessmen to hire cruise ships but acknowledged that there might be a problem with adequate berthing facilities and so a number of the vessels might have to anchor offshore and the spectators shuttled into shore with smaller vessels.
Another United Kingdom-based company, Gulliver Sports Travel Cricketlogistics, which is responsible for accommodation, airline ticket-sales and match-tickets, earlier this year said Guyana needs 485 rooms for teams, officials, media and sponsors.
Authorities said accommodation appears to be the biggest headache, compared to the mainly India-funded stadium being built at Providence, about 14 miles south of Guyana's capital Georgetown.
Civil engineer at the Providence Stadium, Walter Willis, said 80 percent of the civil works on the stadium have been completed but grassing the outfield has suffered a three-week delay because there were some problems getting the grass-seeder cleared from Guyanese customs.
The stadium has a capacity of 15,000 people.
