I'm not what you are looking for but I thought I would throw it out anyway to at least give you the option.
I'm a tall married male (separated) from Ohio (your next door neighbor) looking to share a cabin and other ship and shore activites with someone on a Carnival Cruise departing from Miami on Monday July 9th returning on Friday July 13th. Ports, other than Miami, include Key West and Cozumel. I'm a non-smoker and respectful of others. I'm ok, with an inexpensive inside cabin (you don't spend much time there anyway. Again, I do understand that I'm not exactly what you are looking for but one never knows. Take care, --Mike
