I'd love to go sailing that week! I'm a 28yr old non-smoking female, drama free, and pack light. The Carnival Magic has a sailing out of Galveston for a 7 day Western Caribbean cruise Nov 3-10th that seems like it would fit your schedule. Ports of call are Mahogany Bay, Belize, and Cozumel. The cabin would be $429/person not including taxes and fees.
Feel free to ask me anything you like
