Isle Royale Forums

Went online to book my 6/10 trip on the Isle Royale Line and noticed a spot for a coupon code, does anyone know where I can get one?

I'm guessing this is a feature of their reservation software, but to the best of my recollection, I've never seen a discount code. (And these forum folk would be all over it, if there was!)
It's probably something more likely used (if at all) with their sunset cruises at the mainland that they also offer.

Thanks for responding

if it helps, when you are planning to stay at the Casino hotel in Grand Portage, the Captain of the boat said we get a discount if you say you are the voyager to the island.
