My wife and I will be staying in Philly near the convention center from Sunday to Wednesday but will walk vast distances as that's how we like to explore cities. Alas, we are of somewhat modest means, so the high end recs (while read for vicarious pleasure) don't really work for us. I've already made plans to go to a concert Sunday night at World Cafe Live, drinks Monday night at Standard Tap and the Phillies- Yankees game Tuesday night. Also, we want to hit a BYOB for lunch, Tria for "Sunday school" and the Reading Terminal Market for lunch. As you can tell, we don't mind a full schedule. Any thoughts/suggestions on suitable daytime entertainment would be greatly appreciated. We may be poor, but we're also snobby in that we're not interested in the tour bus stuff but rather really interested in what makes Philly a great city. What should we eat, drink and experience, in short? Couple of random questions, geography/safety wise. Is South Philly between Center City and Citizens Bank Park safe for walking day or night? Also, same question goes for the walk between CC and Northern Liberties. Thanks again for all help and I promise to report back on our experiences!
