It was closed for rehab last year towards the end on August and it just returned to service last month. It was closed for 1 year so that they could work on her hull.
At this time is is only running from 11am until 5 or 6pm. They will be running it for
MVMCP and the Pirate and Princess Parties coming up, but in general it does not run at night time. It used to run from park open until park close, but they changed that a couple years ago as they were not really getting the ridership later in the evenings.
