Shirley, I can understand your not feeling comfortable walking around the Casa Marina. Back in the day when cruise ships had locked gates to keep the "classes" seperate, I can imagine that the Casa Marina kept up an air of "sorry, we're for wealthy visitors, not for townies". And it would be hard to forget that kind of non-welcome even though it's now just a Wyndham (it was a Marriott when we had Christmas dinner there).
And nice as it was... it doesn't <i>"feel"</i> like Key West.
