The kids each earned 4 free tickets to the National Aquarium at downtown Baltimore. We picked a rainy and cold Saturday afternoon and went for the first time. It was a cool experience.
I think the jellyfish exhibit was everyone's favorite. We got to touch some of them too. The Sharks were another highlight. We missed the dolphin training and had to go back another time to see it. We sat at the Splash zone and all got soaking wet by the dolphins! They didn't make a good first impression on Jack for sure :-)
The kids also loved the little music park between the Aquarium and the parking garage. They insisted on playing there in the rain! We'll definitely go back again :-)
