We're headed out to our first cruise in a little over 2 weeks. I'm frantically trying to plan for everything! I want the kids (DS 6 and DS 11) to enjoy the labs but I also want us to spend a lot of time together as a family - especially since this is our first cruise. What are the best times to send the kids to the lab that they won't miss great family activities? Is it true the first night we have to stay with them in the labs?
