Thanks for the reply tothedogs.  I may PM you in the future if we book it.  Sounds like it would be a charter right up our alley.  Only real issue I'm having is finding airfare during that time of the year.  Seems that tickets are either bordering on $2,000 each or you have to spend two days travel time each way - or both.  We are slightly flexible but with three kids we don't want to miss too many school days.  Maybe I'll just have to close my eyes and eat the $7-8K it will take to get my family down there.  Haven't looked for a boat yet but there seems to be quite a few options in that regard - hopefully we'd be able to find one we like.  All-in-all I think the charter sounds like a blast.
