The ship leaves out of Galveston on October 10-17 and the prices are from 450-650 + or -. There is an announcement in the Torch under conventions or some such listing but that is all. If you go to
www.bspcruise.com I think you will find more info. The cruise was supposed to be 5 days but the response was so great that Carnival Lines upgraded to a newer, larger ship and extended the dates to a week for the same price. Ports of call are private island Progreso, Belize and Cozumel and the theme is "Let The Good Times Roll" a la Mardi Gras. Some 700 BSPs have signed up and it looks like it is going to be wonderful, but probably wrong time of year for you.
