Can you exit the Flower Show and come back in later the same day?
Yes, you can exit and return on the same day *if* you make sure to get your hand stamped for same day reentry. You will not be able to re-enter the show without the hand-stamp. Ask the helpful volunteers in pink pinnies to show you where the hand-stamp stations are, before you exit the Show level of the Convention Center.
Thanks for asking, and enjoy the Show!
