CoCo Key Resort on East Main Street in Waterbury permanently closed on Sunday.

The business was open for eight years offered an indoor water park, more than 280-hotel rooms and event space, according to the Waterbury Regional Chamber and employed close to 300 people during peak season.

'It is never a good thing to lose a business, especially a business that can actually attract people to the city. CoCo Key was a fun place to go. You could stay there and go other places in the city,' David Krechevsky, public policy and economic development director of the Waterbury Regional Chamber, said.

Krechevsky said many conferences were held there, including the chamber's Advanced Manufacturing and Stem Expo every November. The chamber now has to look for a new venue for this year's event.

Some people in the community said CoCo Key is a lost asset.

'I work in the community. I think a lot of the families I work with utilized the park. I think it will be missed in Waterbury.” Rob Sarmadi-Fard, of Prospect, said.

Others said it was overpriced and over-crowded.

West Haven on board with new proposal to transform abandoned city conference center 'I have always thought it was expensive, to be honest with you. I mean for a family of four, I know it was kind of a lot. The one time we went on Groupon and we stayed overnight,' Regina Schiavi, of Cheshire, said.

Krechevsky said CoCo Key will be torn down and replaced with a new warehouse that will house Restaurant Depot.
