I thought PNC park was very nice last time I visited, but I don;t know how they are still doing, I'm so wrapped up in the AL right now.
I'm a Flyers fan, and dispise the Pens, so don't go there. Unless you want to use the watch to somehow sabotage the team. Adjust the timing so that it is 90 minutes slow/day, and then get them to use it as a team timekeeper for when they need to arrive at the stadium.
I had a blast in Southside: some great bars and party actions, but I don't know how that would make for a good photo op.
I'm a bit of an art nerd, and while he is not one of my favourite, you have the Andy Warhol museum there - I've never been. Might make for some good arty pics.
