Passport problem, part deux

Well, at least Marazul Charters called me the moment they opened to address my travel nightmare.  So, here is the scoop, according to Neslon. My old passport is, in fact, still valid and I should not encounter any problem either in Miami or in Cuba.  Truth is, I am not that concerned about leaving Cuba, I just don't want to be denied not going on this trip at the starting point.  Do I still have the red itching rash, yes, a bit.  Has this happened before, you bet.   Best advice that Nelson has for me, take both passports.  Okay.
