Katama sounds fun, but not the right time to be doing my first grass landing.
They keep it very well maintained.
Its easier to land there then paved runways. Wider, very smooth. Nothing to worry about. Just treat it like any other runway.
Yep...I did my first grass landing there a few years ago. Very, very easy- and it's one of the longest grass runways in the states. Total non-event, other than the coolness factor of course.
