Our first visit to eastern USA and Phildelphia - we arrive at around 8:30am at the airport, and due to some work issues for the people we're staying with they won't be able to pick us up until early afternoon.
Looking at maps it seems straightforward to catch a train into the city - and it seems the Independence Hall Visitors Centre would be good place to start our visit.
The only issue I have is that we will have our luggage with us - just carry on sized day packs - but obviously we'd prefer to store them somewhere. Also I suspect that security would have a problem with them too!
Any suggestions as to where to leave the bags - happy to pay - it would only be 1/2 a day or so. are there lugage lockers at any of the train stations? Does the visitor centre offer a luggage storage service - I can't find any mention on their website.
