If you have to much stuff to do, no sense putting more stress on by driving. I must say, driving is crazy. I find a huge difference in our highways compared to US highways...there more crowded and fast.

I don't do any of the driving. I offer but DH knows that I would have a heart attack especially in NJ/NY.
It is hard to manage all the people. Of course I let them book their own flights as again we drove. But even down there. My family rented a house, DH and his family stayed off site until two days before the wedding. I felt I was driving everywhere's to see family. Then we had to coordinate getting everyone to Tampa for a NHL Hockey game, then to NASA, then some did the Richard Petty Driving.
And as stressful as it is now. When the wedding day arrives it will be all worth it and you will be on
Sorry for my rambling. And I hope everything works out.
