Hi. We'll be staying overnight in Te Anau and are thinking about trying to catch either the earliest Mitre Peak Cruise boat which leaves at at 9am or the latest one, which leaves at 4:30pm. Either option will give us time to do a short hike mid-day. BUT we don't want to depart or return in the dark. Haven't figured out how to find day length information for that area. What can we expect in early November? Thanks!
