Preface that I have not flown post 9/11 and am a huge chicken when it comes to flying. But the promise of 2 days at universal in addition to our disney stay resulted in us flying. And I know nothing about it now. A few ?'s will my children need a photo id? Can I carry on snacks for them like a fruit rollup and cheerios? no liquids I get. Are there restrictions on electronics? Like a laptop? Anything major I should know about? or Minor? Oh and what rental car company has their pickup AT THE AIRPORT- not a shuttle bus away. Thank you information will calm me down.
