Last tender

Traveling on Holland America in May and it says we are in port until 3. An excursion through the ship is offered at one, but we are planning our own through a private tour company. Theirs sounds the same and leaves at 12:45, but the late time makes me a little nervous. The tour lasts an hour. What time will likely be the last tender?

The last tender is likely to be at around 2:00 PM.
