Laurajean1014,
Breath deeply and smell the flowers (they're all over the place).
If you see a group of people wearing the same T-shirts, go the opposite direction.
If all the parks are crowded, go to Epcot, sit back and enjoy The British Invasion, Off Kilter, and the Voices of Liberty (over and over again!). Then get some ice cream (try the "Kitchen Sink") at Beaches & Cream at the Beach Club.
Have a great time!
