Well, the Madonna concert was of course, our favorite part of the trip. She was AWESOME. People from all walks of life came together for her first U.S. performance in 9 years. First Union Center was a great place to see it!
There seemed to be many cool and interesting restaurants and bars in the Historic District and it was so neat to walk around in! The old brick buildings, cobblestone streets, AWESOME weather, guys dressed up as revolutionary war soldiers...
Of course, the historical value of Philadelphia is amazing. We only had a chance to visit a few major sights (the U.S. Mint, Penn's Landing, Independence Hall, Liberty Bell, Betsy Ross's house, and the Hard Rock Cafe :) ), but I highly recommend you visit the places where our country was founded!
South Street was definitely a nightlife experience I won't forget. Lined with people, cars, shops, restaurants, and bars, it is one busy crazy street! We went down there after the concert to check out a couple of bars and had a lot of fun! I'm not sure how "safe" the street really is, but it seemed ok to us.
Quick Tips:
I'm sad we missed it, but I would have liked to see the LOVE statue in the fountain in the art/museum district. You should go see it!
Subway Safety: During the day, we took the subway from Center City back to our hotel, and there weren't that many people down there on a Sunday, and it seemed safe, until (what we think) a guy tried to grab my purse. He didn't, and was gone before we realized what he was trying to do. (My precaution: Don't stand near the exit gates...gives thieves a quick-grab-and-getaway)
Best Way To Get Around:
On the way to our hotel from the airport, we took a taxi. There is a law (we heard ALL about it from our driver) that they are not allowed to charge more than to/from the airport to anywhere in DT Philly, so that should be your fare.
A taxi ride to anywhere else is .60 initial fare, with .30 for every 1/6 of a mile driving, and .20 for every minute spent waiting. It was to go from our hotel (in the historic district) to First Union Center.
The subway: We heard it was unsafe, but after talking to policeman, he assured us it would be safe for us to take it from First Union back to our hotel. We were charged a person. Not bad, but we found out later, that they were overcharging (there was police investigating in the subway tunnels)! It should have been .60 for 2 people. Oh, well. So, we felt safe until we had to interchange closer to DT Philly. Then we didn't feel so safe.
Also, walking almost anywhere in Philly is easy, cheap, and safe!
