Well, thanks for the tips. I got back a few days ago. I was only able to spend 3 days and 3 nights in the city and not the whole week I was hoping for. Here’s what I was able to do when I wasn’t attending conferences.
I stayed at the Loew’s Hotel in the PSFS building - that was architecturally interesting, but I didn’t have time to tour the upper levels. It’s listed as a 4-star hotel, but the service was anything but …
On the first full day I was able to visit Independence National Park - Independence Hall, Independence Square, the Visitor Center, and the Liberty Bell. I understand security down there is a little nuts - but I waited in line for an hour to get into the Hall - and there were about a dozen rangers wandering around doing nothing to speed the process along. In the evening I wandered around Center City, the Old City, and the theatre district. My coworker and I stopped in at a hole in the wall restaurant and bar for dinner where I learned a valuable lesson about finding out what kind of place it might be ahead of time
The food was great though.
On Day Two, I stopped in at the Mint, but was turned away by a security guard who thought I would find the gift shop a lot more interesting than the now off-limits tour. In the early evening, I visited Reading Terminal Market for a bite to eat and then took a long walk down the parkway to the Philadelphia Museum of Art, stopping at the Rodin Museum along the way. Except for the concert int he main hall, there was ahrdly a soul in the place. I was shadowed by security guards in every single room and given conflicting advice by several of them. It was like they’d never seen a guy with a backpack before! Fascinating place, though. I hadn’t realized the collection was THAT good. A whole room full of Monet. wow. I could have easily spent two days there. Some of my best photos from the trip were taken at the museum.
On Day Three, I went to the Washington Square / Dock St area to photograph more colonial buildings including Carpenters Hall and Elfreth’s Alley. I was too early to get into the 2nd national portrait gallery and the Exchange is no longer open to the public. I had dinner at McCormick’s, not bad, but Legal Seafood is better. That evening I went to Penn’s Landing and then to the Seaport Museum for a private party. I had been walking everywhere, but this time I took the subway and got off just before all the nightclubs and cafes. Got some great night photos of the Ben Franklin bridge, Penn’s Landing and the old warships. I didn’t have time to visit the museum during the day, though.
I did a LOT of walking on this trip to see the real city, so I saw a lot of people as well as a few landmarks along the way. I was surprised at the number of sidewalk vendors, protesters, and aggressive panhandlers. It was worse Boston!
I was also surprised at how quickly the city shuts down in the evening. Excepting bars, almost nothing is open past 5pm. Unfortunately service was generally poor in most places. I had breakfast in the hotel restaurant, which was supposed to be a good pick but it took twenty minutes to get an order taken and half an hour to be served what amounted to toast with very few customers in the place and no apologies from management. In other places, service was slow and unfriendly as though they couldn’t be bothered to deal with actual customers. Rangers and security guards were surly for no particular reason. Walking through the museum, I felt like a known shoplifter. On the positive side, it’s a very cosmopolitan city. It’s as interesting or more so than Boston, the nearest big city I’m familiar with and have lived in. Lots of interesting things to do and see during the day. The museums alone would keep me busy for a week or more. When the security situation is squared awaya nd construction is finished, the old city will be a lot more fun. Although my first visit to the city was a tempered success, I’m excited enough about what I saw to convince Mrs. evilhanz that we should take a personal trip to the city. She’ll get a big kick out of seeing the Wannamaker building when I start singing " … and we can BUILD this bridge together …". 
Oh by the way, what the heck is a Wawas?
