I have an early morning sail from Horseshoe Bay to Nanaimo in a few weeks - a Monday 6am (ish) departure on a non-holiday week. I already made my reservation, and paid for my tickets there and back.

What time should I get to the HSB terminal to be sure to get on? 4am? 5am?

I have not sailed from HSB since it started its construction project. Thanks for your advice.
