You have my sympathy. From childhood one of my brothers snored with roars the likes of which I did not hear again until the Jurassic Park series. Perhaps you could have meets without an overnight until your machine-assisted sleeping issue is fully explained to him face-to-face. I say continue the chase. The only cost to you will be some time.
I don't really get it either. After some thinking, I'm thinking the sign is intended to advise motorists looking for the cruise ships that they must use the airport exit to get to the cruise ships. Aside from that, the concept is pretty funny.

I have noticed that the fantasy that is squatting in this image appears in several of your postings. Are you harboring any need-to-know information?
