We're visiting Salem the first week of October and we're going to take the Hocus Pocus tour first because we're arriving early in the week. Then we plan to walk around and see most historical spots throughout the week. By that point, would it be pointless to take the "Tales & Tombstones" Trolley Tour? Or does it go to more spots that you won't see by walking the city? Also, does anyone know of any other cruises besides the Mahi Mahi company? Thanks!
