Can I buy my ticket when I get off the cruise ship Sept 18 ? I'm interested in the scenic overview tour - 90 minutes - senior rate $23.00
How often does the tour go out throughout the day
You can purchase your ticket at the visitor's information center, which is where the tour begins. I think it departs every hour, maybe more frequently. It's a 90 minute ride from start to finish, but you can also hop on and off at various points.
