My next 5 trips for work: Portland, ME; Niagara Falls, NY; Albany, NY; Shelton, WA and Chicago, IL.
I have found activities to do in Portland, ME. The LL Bean store, Longfellow Home, Victoria Mansion, Down east Duck Tours.
In Niagara Falls, I don't have as much time so I will of course hit the Falls preferably at Night, maybe do the Maid of the Mist tour for $13.50 and see the Daredevil Museum. The museum is free.
But the other cities not a clue! I have my work cut out for me to find CHEAP activities. Any recommendations?
