I am in Carlsbad, I noticed your post.
I know a gal in La Jolla that is always looking for a cabin mate.
I myself will not take the chance sharing a cabin with anybody unless I was attracted to that person and vs versa.
I can put you in touch, her name is Cynthia.
Cynthia called me yesterday, she booked Carnival back to back from San Jaun in two weeks.
She wants to hook up for Sushi today.
