Just to add to @gramps post above, you will have priority on the first boat if staying on either of the islands rather than just being a day visitor. Or that was the case when I've stayed there in the past.
Hmmm ok I'll become a member then, thanks! Would be nice to see the puffins with the sand eels, but not the end of the world if I can't get those dates. I've never seen a puffin, so I'll be stoked either way![]()
