Also some good recommendations for night life could come in handy, I'm 26.
Annapolis is a good place for water oriented things, including boat rides.
As for gardens, there's Longwood Gardens in Kennett Park, Pennsylvania. It's a bit over 2 hours from where I live, so probably just over an hour from Baltimore. Meadowlark Botanical Gardens in Vienna, Virginia is fine, too (again, a bit over an hour from Baltimore). Closer at hand would be the National Arboretum in D.C. I believe there is also some botanical garden in Wheaton, MD, but I'm not sure why I believe that. There's also the American Chestnut Land Trust down in Calvert County.
I'm not a big night life person, but I do know the theatre scene reasonably well and can point you at the Hippodrome for touring productions and Centerstage, and the Lyric. Again, if you are more specific about what type of night life you want (music, dancing, theatre), you might get more helpful answers.
