Repost - Baltimore over Spring break

DH and I booked a hotel in Baltimore inner harbor during Spring Break. Going the Thursday after Easter till Saturday.
Anyone been there that time? Will it be nuts? WEll, too late at this point. LOL!

Can you recommend places to go, what to see and do with the kids? Restaurants?
The boys are 5 and 3.

Definitly want to do the aquarium and something on the water.
Any boat tours I can book?
Do I book anything in advance or just do it while we're there?

Thanks!

Besides the aquarium, Port Discovery is really cute for kids and I highly recommend going there. Walking around the Harbor, there are usually street performances going on and they try to include children. There are a number of boat tours that you can take, some you can purchase that have lunch or dinner but I think just taking the water taxi over to Fells Point for a meal is enough. Also, the Maryland Science Center is walking distance. There is also a nice carousel that my daughters used to love going on.
