Yesterday while in Phoenix we went to the Sea Life Aguarium http://www.sealifeus.com/phoenix/phoenix-home .
They stamp your hand at the door, so you can go through as many times as you want until the end of day. We took two turns around. After starting out together, Optimus and Hubby went off on their own. Tink and I hung back so that she could draw in her Aquarium book.
