The $31m renovation of the 31-storey Miami Marriott Biscayne Bay in Florida, US, has been completed after two years.

The renovation involved a $17m investment in the redesign of 600 guestrooms and suites, streamlining public areas and a new lobby.

The project also included a new waterfront dining area, a cafe, a boardroom, a ballroom and a fitness centre.

The redesigned hotel features 6,096m² of meeting space and event venues, a pool and a grill bar.
