Perhaps but there are a bunch of platinum cruisers on this forum that don't live in Florida.
I live in Houston, Texas.this forum is comprised of like-minded Disney die-hards who patronize the parks, cruise line and invest in DVC. Would venture this microcosm is not necessarily representative of the real world. However, it would be very interesting to know the geographic breakdown of the platinum cruisers. Not holding my breath for DCL to divulge that proprietary info.
