Be sure to take the most comfortable shoes you can find (Crocs are everywhere!) and bottled water. It's easy to forget to keep hydrated, and drinking the water will make your tote bag lighter!
Weather outside can be HOT and muggy, but inside (especially the classrooms) can be COLD, so take a sweater or light jacket.
