Flight
Its easiest to fly into the Philadelphia airport. There are lots of car rentals and the airport is only about 20 minutes from downtown.
House Or Rental
If you don't want to stay in a hotel, there are lots of options available on airbnb. We recommend staying in the fairmount or spring garden/art museum neighborhood. It's close to downtown and to most of the wedding events. If you can't find anything there, Center City, Rittenhouse, Northern Liberties, Graduate Hospital, Old City, and Bella Vista are all good areas to stay in.
Hotel
We do not have rooms reserved at any specific hotels, but any of the hotels in center city are great options and easily accessible to all wedding events
