Flying is no big deal. Just like taking the bus. Nothing to worry about. As for flying in the daytime, there is no difference in flying at night. Some flights have to be done at night. I've flown to Hong Kong, Europe, etc - they will be overnight flights everytime. I'm getting ready to fly to Hawaii, and the return flight is overnight also - just sleep for a few hours, or read a book.

For WPB - that is a very short flight, a little over an hour, nothing to worry about.
