Geez doing all parks in one night is pushing it! I've done 2 in one day and it was still tight! Plan on what rides attractions you really want to see or do
and limit yourself to those so that you have time to fit everything in. Also, fastpasses are your friend- even though the parks arn't crowded. 
Catch
the 3:00 parade at whatever park you happen to be at- theyre lots of fun if you like to see the characters. Definatly watch a night show at closing. There is a
fireworks show at MK and Epcot, but I'm biased twordes Fantasmic! at MGM cause I used to work there. It doesn't play every night anymore, but it
will be playing tomorrow at 8pm- its a great way to end the night!
