Hi there, and yes :o( there is a fee for the Sanctuary, I can't remember for certain but the figure of $15 per day comes to mind.
They do sell longer term passes as well, and I have it in mind that days in port were less than days at sea.
Having said all that, the last time we were on Grand, the "never-ending" pool below the sanctuary & it's two whirlpools were still free :o)
It was a nice quiet area albeit shaded around the pool, so the bench seating that steps up/down to is was in use for sunbathing.
Hope this helps,
Alan & Katrina
