After many years of cruising solo and a couple voyages with my sister and brother-in-law, the rest of my siblings and mother finally got on board (so to speak) and agreed to give it a go. A couple weeks ago, we booked a cruise on the Reflection (Celebrity) for January 2017. We have a bit of a wait but all are very excited to set off.

I am interested in hearing opinions...  

What made or broke your family and group cruise experience(s)? Any suggestions for avoiding the risk of ending up "too-close-for-comfort"?
