We were in the rear of Conch, overlooking the marina. No MK view--just a view of the construction crane and trucks where the Electric Water pagent is stored. But we easily walked down to the steps of the building to see the fireworks.
Plus when the marina boats were in use (most of the day!), we couldn't use our balcony because of the strong gas smell. We were on the 3rd floor. If our stay had been longer than 2 days, I would have requested another room.
