First time me and my family are going on a cruise and we picked disney fantasy. We are doing it in October so it will be the Halloween on high seas. It's a 5 day cruise what should I expect from all this. I do want to do a date night with my wife at remys but don't want the kids to miss anything fun or super important. What's the best day to go to the dinner someone suggested at the private island or the first sea day.
