The CoCo Key Hotel & Water Resort Boston-North Shore marked the beginning of a $10 million-plus renovation that will convert the hotel into a DoubleTree by Hilton in the fall, hotel management said.

The Danvers hotel, with 365 rooms, held a demolition kick-off event for the renovations this week.

Planned improvements to the hotel include upgrades to the meeting space and the addition of new technological amenities that address the needs of the business traveler, such as 50 mb fiber optic high speed Internet and an executive lounge.

With an adjacent 65,000 square foot indoor water park, the hotel also caters to families and leisure travelers.

After renovation is complete, the hotel will be re-branded as the DoubleTree by Hilton Boston-North Shore.
