We have early dinner. I also can't see myself eating at the time I'm usually in bed.
I will set your email address up in the girls address book. They each have their own email account (under our main account) and since it is a kids account, I severely limit what they can do. No attachments, etc. If your daughter wants to send pictures, I will have her send them to my account.
I think they will be thrilled to meet someone they will be cruising with, especially someone who knows the ropes. It will make them feel more comfortable to know someone when they get there. Being young teens is a socially tough time. I have one that is very outgoing, and the other is very shy.
