I have a tour I'd like to book that is with someone else besides Disney (I didn't like any of the tours available through Disney for Aruba.) We're supposed to be able to go Ashore at Aruba at 8:30 AM and the tour starts at 9:30 AM. It only takes 15 minutes to get to the tour. Is the Cruise ship likely to dock too late for us to get there? Honestly, an hour seems like enough leeway but I thought I'd get some opinions or experiences others have.
