Our DD will be 11 on the cruise, and has always loved the clubs! She usually does a lot of the crafts and activities, and makes friends to do things with. Being an only, we worried on our first cruise, but she's always loved it!
She's looking forward to bring in the Edge this time around. I'm not too sure about it, but we'll see how it goes!
Does your daughter have face time? We could try to have them meet ahead of time. Maybe mine would be more open to the clubs. I have an 18 year old that does not live with us so my dd is like an only child. Let me know if they could somehow hook up before the cruise
