Yes, regs and insurance may be significant issues at many venues sad to say at any Park, Boca Chita, Bahia Honda, etc.. Anyway, here are some more ideas.

Cocoplum Beach and Sombrero Beach in Marathon. I found this cruising down the Keys via Googleearth.com. It looks like they might open up from ENE to E to SW. Not great if a strong NE front comes through but it is just one more idea.
These beaches are a few miles to the north of the campground described a couple of posts above this.
Still more about beaches in the Keys appears at:
