I think I would be inclined to treat him like any new guy you would date.
If he was a relative stranger, you would take it very slowly with a young son. Plus, you would have standards that you would not back down from.
Inviting him to Disney for a week is just WAY too much in my opinion. Any guy would have to be pretty "in" to get that much of your precious time. Remember to value YOU first!
I think you need to work on that--you have standards and values that he must COME UP TO. Make sure your life is very, very full of positive things that you won't DROP just to get him.
You already know what "works", since you got him once before. Relax. You can do that again. Make him work for it--did he work for it the first time?
