Yes you will. My DH and ds did it two weeks ago. They were scheduled to come back at 3:00 pm but some people were late getting back to the ferry to bring them back. So they got back at 3:45 and we still had time to get to some of the stores. They say on the boat that the stores close at 5:00 but we asked the water taxi and they said that most stores stay open till 7:00pm. I guess that is because Disney is there till 7:30pm. Also beware that Front street is torn up because they are doing renovation work, so you have to be carefull walking at night.
