Bowel incont.

I suffer from B.I. and have to go for a family reunion on a cruiseship for seven days.!! (Im so nervous!!) Have any of you with similar symptoms taken vacation before, please offer your advice and what your experience was. Id really really appreciate I worked up even thinking about it and the trip is not until christmas time. Waiting to hear some useful tips. I only been on very short trips, have managed them OK. I just prefer to avoid anything that is more than a weekend long LOL
