For those who are visiting or new to the area, this is a summary of the major hobby zones in and around Philadelphia.  
 
Philadelphia:
 
Center City ("CC") is the main business and cultural part of town. This area features many hotels, restaurants of all types, the area's finest museums and cultural points and other amenities. CC is best for businessmen who can break away during the business day. The lack of free parking is an obstacle to some hobbyists, but some of the hotels in the airport area also charge for parking. Another issue is that some of the better hotels require a key card to activate the elevator, so some maneuvering may be required. As would be expected, hotel prices are generally higher than in the suburbs.
 
More towards the river are the Independence Hall, Society Hill and Penn Landing areas.  There are a few nice hotels, including some new boutique venues, in these areas along with many fine restaurants, historic sites of interest and diverse shopping opportunities. Just a note: the Penn Landing area is a bit isolated if you want to move about.  
 
King of Prussia:
 
Another big Hobby area is King of Prussia ("KOP"). This a western suburb marked by two large shopping malls, many hotels and restaurants.  This area is very convenient for the many mongers who lie in the western suburbs.  The downside is that it is a trek for those who live in CC, the eastern suburbs or New Jersey. Also, LE is supposedly most active in KOP, but you see lots of ads for ladies setting up shop in KOP. Just be careful. Transportation can be a problem in the suburbs, so it would be wise to see what hotels have shuttles to either the airport or the 30th Street Amtrak station.  Some ladies take the local train service (SEPTA) from the central 30th Street to reach nearby Norristown, then taking a cab or shuttle to get to the hotel.
 
Plymouth Meeting and Willow Grove:
 
Two other active suburban areas are Plymouth Meeting and Willow Grove. These areas are east of KOP near the PA Turnpike and also have malls, restaurants and hotels, but less LE activity. Transportation can be a problem in the suburbs, so it would be wise to see what hotels have shuttles to either the airport or the 30th Street Amtrak train station.  Some ladies take the local train service (SEPTA) from the central 30th Street to reach nearby Norristown, then taking a cab or shuttle to get to the hotel.
 
Airport Area:
 
This is a favorite nesting area for ladies and hobbyists because of its many moderately priced hotels, the availability of free or cheap parking and the relative anonymity of the place. There are few amenities in the area. Travelers can get to CC by hotel shuttle, a train or by cab. There are paid shuttle services that go to the hotels in South Jersey and the PA suburbs.  
 
New Jersey Suburbs:  
 
The South Jersey towns of Cherry Hill and Mt. Laurel are busy hobby destinations since they are near the New Jersey Turnpike, I-295 and are not far from Philadelphia. Traffic seems to be less of an issue and hotel prices are lower. LE in Mt. Laurel is more active than in Cherry Hill. A car is a help because cab service is spotty but maybe Uber is improving the situation?
 
Another South Jersey area is Deptford which has many hotels near a major shopping district just few minutes away from the Philadelphia using the Walt Whitman bridge.
 
Philadelphia Area Attractions:
 
The Benjamin Franklin Parkway has five great museums and is a nice place to walk when the weather is fine.  For adults the top three are the Philadelphia Museum of Art (huge, diverse and extraordinary collections in a magnificent building), the Rodin Museum (concise collection of Rodin's major works in a recently renovated venue) and the new Barnes Foundation (impressionism gone wild in a new building).  The Benjamin Franklin Institute specializes in science and technology and is great for kids and adults.  And then there is the Museum of Natural History.  
 
The Independence Square area has Independence Hall, the Liberty Bell, Betsy Ross's house and other historical sites.  The nearby Society Hill area has 18th Century homes, great shops and restaurants and a little further south is funky South Street, although that area can be dicey for attractive women traveling alone.  
 
Public transportation is generally by bus, subway and there are lots of cabs. Regional rail can get you to the suburbs
