What a great kid she is, your Lauren. You've given them hope for the future Mick. That is a beautiful gift from a Da to their children.
Plan the holiday of a life time!!! Try not to focus too much on cost (I know, I know, we all are governed by money in the end) and do all those things you've always wanted to do and didn't!
This is going to be such fun watching you (and helping a bit where we can) plan this incredible holiday.
