Celebrity dream visit

A few people have asked me which celebrity I'd like to spend a day with. There are a few, but at the top of my list would be John Travolta. Why? He seems like a genuinely nice guy and I would want to take advantage of the fact that he flies his own aircraft. So that I could fly with him. So that's my choice.

If John wasn't available, I'd have to go with Tom Hanks for the nice guy factor.
