It was $1 day at the Baltimore Aquarium (versus a normal $40 per person). We waited in the line, which wrapped around the entire large building and snaked here and there, for over an hour and got our tickets for a little later in the afternoon. We walked along the harbor towards the German Christmas Village. We did the traditional browsing, mulled wine drinking, and brat and strudel eating. Delicious and delightful. Then we went to the aquarium. Parts of it were really neat, certainly not worth $40. The main first exhibit is the entire floor is the fish tank swimming with tons of fish, sharks, turtles, stingrays, etc. Another neat exhibit was the jellyfish, which I created a video of. Enjoy!
