One of the advantages of being interested in history, raising kids, and just being around for a while: seen a lot of museums and stuff - but most of the time not into the naval side as much.
Even so, been on the USS North Carolina in Wilmington; the U505 in Chicago; the USS Massachusetts, USS Joseph Kennedy, the Hiddensee (a russian built missile corvette; USS Constitution in Boston; the USS Becuna (Balao class fleet sub); USS Nautilus (first nuclear powered sub). The USS Olympia was closed when we were in Philly. Not sure where, but I know I've been on a ww2 era DDE.
