No, I'd go; there's enough history to make it worthwhile in spite of the tourists. And I'm probably jaded 'cause I've been there three or four times already.
personally believe if you look like a tourist, you look like a target.
Amen to that. I'm always giving my family a hard time whenever we go anywhere about pointing and taking pictures of every little thing. To me, that's like holding a big sign over your head saying "LOOK AT ME! I'M A TOURIST! PLEASE MUG ME!"
Cheese Whiz?

No way. Either American or very mild Provolone is what you
should be putting on your cheesesteaks. Oddly enough (while we're speaking of tourist spots and cheesesteaks), the best cheesesteak I ever had was at a little shack in Lexington, Massachusetts.
Pick your jaws up off the floor, you're leaving puddles.
It's a long story, but it turns out the guy who ran it was from Philly and had retired out to Lexington. No idea what the name of the shack (yes, it literally was a shack) was or where exactly it is, but if you're in/from Lexington and you find it, let me know. I NEED TO GO BACK!!!!!!!
